Embodiment

Please refer to Fig. 2 A, Fig. 2 B and Fig. 2 C, Fig. 2 A, Fig. 2 B and Fig. 2 C be respectively the overlooking of the embodiment of the invention one indicator device 20, side-looking and etc. the visual angle synoptic diagram.Shown in Fig. 2 A to Fig. 2 C, the outward appearance of indicator device 20 is comprised of a housing CS and a locating shaft loam cake P_CAP.Housing CS comprises a loam cake CS_UP and a base CS_DW, combines by snap fit and draw-in groove between the two.Locating shaft loam cake P_CAP is preferably the insulation material and forms, the size of the visual indicator device 20 of user is passed locating shaft loam cake P_CAP with single finger, or with many finger running fix axle loam cake P_CAP, with travel direction control, operate in detail hereinafter explanation.

Inner structure about indicator device 20, please continue with reference to figure 3A, Fig. 3 B and Fig. 4 A, Fig. 4 B, Fig. 3 A is the birds-eye perspective of indicator device 20, and Fig. 3 B is the cut-open view along the G point of Fig. 3 A and G ' point, and Fig. 4 A and Fig. 4 B are respectively the side-looking of indicator device 20 and wait the visual angle to assemble synoptic diagram.In the housing CS of indicator device 20,, comprise a locating shaft P_AX, an annular fixing member FX, an elastic component EL, rectangular conductive sheet MT_X, MT_Y and a base plate BS from top to bottom.Rectangular conductive sheet MT_X, MT_Y be quadrature each other, and includes hollow chute, and locating shaft P_AX then passes both laps.Annular fixing member FX is located on the locating shaft P_AX, and its outside is coated with elastic component EL.After assembling was finished, annular fixing member FX and elastic component EL were arranged in the cavity UP_SP of loam cake CS_UP.Cavity UP_SP has sufficient space, can make locating shaft P_AX (or locating shaft loam cake P_CAP) stressed after, mobile in proper range, elastic component EL then can when external force disappears, return back to initial position with locating shaft P_AX.In addition, base plate BS is used for supporting rectangular conductive sheet MT_X, MT_Y, and it can be the printed circuit board (PCB) that layout has a control signal generation module, is not limited to this.

Specifically, please refer to Fig. 5, Fig. 5 is rectangular conductive sheet MT_X, the MT_Y of indicator device 20 and the synoptic diagram after the base plate BS assembling.As shown in Figure 5, rectangular conductive sheet MT_X, MT_Y be quadrature each other, and the central authorities of both chutes form a space S PS.Space S PS is in order to holding locating shaft P_AX, that is locating shaft P_AX passes the overlapping formed space S PS of chute of rectangular conductive sheet MT_X, MT_Y.

The function mode of indicator device 20 then is described, please refer to Fig. 6 A and Fig. 6 B, Fig. 6 A is indicator device 20 when not being subjected to external force, the skeleton view of locating shaft P_AX, rectangular conductive sheet MT_X, MT_Y and base plate BS.Suppose that locating shaft P_AX is subjected to corresponding to towards the External Force Acting of an arrow XR time, then locating shaft P_AX can drive rectangular conductive sheet MT_X, MT_Y and slides at base plate BS, and becomes the situation shown in Fig. 6 B.By Fig. 6 B as can be known, the center line of rectangular conductive sheet MT_X has moved a distance B S_X, and the center line of rectangular conductive sheet MT_Y has moved a distance B S_Y.Distance B S_X and distance B S_Y can reflect its content of operation corresponding to user's the power of controlling.

From the above, when mobile, locating shaft P_AX can drive rectangular conductive sheet MT_X, MT_Y and move corresponding distance when locating shaft P_AX is stressed.That is to say that when not being subjected to external force, because the effect of elastic component EL, locating shaft P_AX is positioned at rectangular conductive sheet MT_X and both centers of MT_Y.When locating shaft P_AX is subjected to external force and produces displacement, according to direction and the size of external force, locating shaft P_AX can be offset the center (another kind of saying is that external force is removed initial position by locating shaft P_AX with rectangular conductive sheet MT_X and MT_Y) of rectangular conductive sheet MT_X and MT_Y.And when external force disappeared, the elastic reaction of elastic component EL can be retracted locating shaft initial position, i.e. both centers of rectangular conductive sheet MT_X and MT_Y.Therefore, be subjected to outer effect and when mobile, as long as know the edge of rectangular conductive sheet MT_X, MT_Y to the distance of locating shaft P_AX, can judge user's the demand of controlling as locating shaft P_AX.

To judge correctly that the distance that locating shaft P_AX is moved by external force has its complexity, in fact, still have other modes can judge user's the demand of controlling.For instance, please refer to Fig. 7 A and Fig. 7 B, Fig. 7 A is that locating shaft P_AX is not when being subjected to External Force Acting, the synoptic diagram of being looked towards rectangular conductive sheet MT_X, MT_Y and locating shaft P_AX by base plate BS, when Fig. 7 B then is subjected to External Force Acting corresponding to an arrow B R for locating shaft P_AX, the synoptic diagram of being looked towards rectangular conductive sheet MT_X, MT_Y and locating shaft P_AX by base plate BS.Wherein, terminal A, C represent the central point of the two edges of rectangular conductive sheet MT_Y, and terminal B represents the central point at the edge of rectangular conductive sheet MT_X, and end points O1～O4 represents the intersection point of rectangular conductive sheet MT_X and MT_Y.At first, for for purpose of brevity, below with L[A, O3] represent terminal A to the length of end points O3 shortest path, with L[O3, B] represent that end points O3 is to the length of terminal B shortest path, with L[A, B] represent terminal A to the length of terminal B shortest path, with L[B, O4] represent that terminal B is to the length of end points O4 shortest path, with L[O4, C] represent end points O4 to the length of end points C shortest path, and with L[B, C] represent that terminal B is to the length of end points C shortest path.In other words, L[A, B]=L[A, O3]+L[O3, B], and L[B, C]=L[B, O4]+L[O4, C].In addition, in housing CS, locating shaft P_AX stressed mobile scope can be by the length restriction of rectangular conductive sheet MT_X and MT_Y, and with present embodiment, length L [A, O3], length L [O3, B], length L [B, O4] and the maximum value of length L [O4, C] equate that minimal value also equates.If represent respectively above-mentioned maximum value and minimal value with max_T and min_T, then the numerical range of length L [A, O3] and length L [O3, B] can be expressed as:

Min_T L[A, O3] max_T, and

min_T?L[O3，B]max_T。

Cooperate again

L[A，B]＝L[A，O3]+L[O3，B]，

After then ought obtaining length L [A, B], can be in two-dimentional coordinate system, define a limited line segment or a bit (when length L [A, B] when just equaling 2 * min_T or 2 * max_T).In like manner, after obtaining length L [B, C], also can be in two-dimentional coordinate system, define a limited line segment or a bit (when length L [B, C] when just equaling 2 * min_T or 2 * max_T).In same coordinate system, corresponding to the intersection point of two limited line segments of length L [A, B] and length L [B, C], can represent the situation of the stressed rear movement of locating shaft P_AX.

In simple terms, because length L [A, B] and length L [B, C] for to be relevant to the position of locating shaft P_AX, and be subject to the length of rectangular conductive sheet MT_X and MT_Y, therefore, after obtaining length L [A, B] and length L [B, C], can judge two corresponding limited line segments, and the intersection point of two limited line segments is namely corresponding to the position of locating shaft P_AX.Should be noted at this and since end points O3, O4 with respect to the position in the axle center of locating shaft P_AX for fixing, and end points O3, O4 are also identical to the distance of terminal B.Therefore, in the process of judging length L [A, B] and length L [B, C], end points O3, O4 can be considered same point, and the mobile situation of end points O3, O4 is the mobile situation of locating shaft P_AX.In other words, need not calculate terminal A, B, C to the distance in the axle center of locating shaft P_AX, and can utilize the relation of terminal A, B, C and end points O3, O4, judge the distance that locating shaft P_AX moves.Certainly, aforementioned concepts be because intersection point O1～O4 of rectangular conductive sheet MT_X and MT_Y corresponding to foursquare 4 points, in other embodiments, end points O1～O4 is not limited to corresponding to foursquare 4 points, and the intersection point of rectangular conductive sheet MT_X and MT_Y also is not limited to four, can also greater or less than 4, decide on design requirement.

The mode of judging length L [A, B] and length L [B, C] has many kinds, and wherein an example can realize by the mode of measuring resistance.Usually know that such as this area tool the knowledgeable knows, the resistance value R of a conductive body can be expressed as:

R＝ρ×LN÷AR，

Wherein, ρ represents the resistance coefficient of conductive body, and LN represents the length of conductive body, and AR represents the sectional area of conductive body.

Therefore, under the situation of all immobilize at resistance coefficient ρ and sectional area AR when very little (or its impact), such as a rectangular conductive sheet, then its resistance value R is directly proportional with length L N.Whereby, get back among Fig. 7 A and Fig. 7 B, as long as the resistance value of measurement terminals A to the resistance value of terminal B and terminal B to end points C, can be by suitable conversion, it is corresponded to length L [A, B] and length L [B, C], and then can learn the situation of the stressed rear movement of locating shaft P_AX, to judge user's the demand of controlling.

Therefore, please refer to Fig. 8, Fig. 8 is the synoptic diagram of the embodiment of the invention one control signal generation module 80.Control signal generation module 80 is used for indicator device 20, and it can be formed on the base plate BS, or otherwise with indicator device 20 combinations.Control signal generation module 80 comprises a resistance detection unit 800 and a converting unit 802.Resistance detection unit 800 is couple to terminal A, B, C, is used for detecting the resistance value R_BC of terminal A to the resistance value R_AB of terminal B and terminal B to end points C.802 of converting units are judged the mobile situation of locating shaft, and are produced according to this control signal DR_CMD according to resistance value R_AB and R_BC.Wherein, should be noted to terminal B and terminal B to end points C the part path overlap is arranged by terminal A, be the accuracy of guaranteeing to detect, resistance detection unit 800 can first detection resistance value R_AB, and then detection resistance value R_BC.In addition, the running concept of converting unit 802 is first resistance value R_AB, R_BC to be converted to length L [A, B], L[B, C], again by length L [A, B], L[B, C] draw the mobile situation of locating shaft P_AX, and produce whereby control signal DR_CMD.Should be noted, when transfer resistance value R_AB, R_BC, except the material that should consider rectangular conductive sheet MT_X and MT_Y, thickness, also need consider the intersection point of rectangular conductive sheet MT_X and MT_Y.

For instance, when the intersection point of rectangular conductive sheet MT_X and MT_Y is four end points O1～O4 shown in Fig. 7 A, then resistance value R_AB is merely only determined by the resistance of terminal A to end points O3 and end points O3 to terminal B, still needs and considers the impact of other intersection point (end points O1, O2, O4).In like manner, resistance value R_BC still needs and considers the impact of other intersection point (end points O1, O2, O3) except being determined by the resistance of terminal B to end points O4 and end points O4 to end points C.In this case, for ease of calculating, can suitably with the intersection point minimizing of rectangular conductive sheet MT_X and MT_Y, make reduced complexity.For example, decide on material or related needs, conductive material only can be coated on one side relevant with end points O3 on the surface of contact of rectangular conductive sheet MT_X and MT_Y, the material that maybe will insulate is coated on the surface of contact of rectangular conductive sheet MT_X and MT_Y one side irrelevant with end points O3, makes the intersection point of rectangular conductive sheet MT_X and MT_Y be kept to end points O3.Thus, resistance value R_AB determines by the resistance of terminal A to end points O3 and end points O3 to terminal B, and resistance value R_BC is determined by the resistance of terminal B to end points O4 and end points O4 to end points C, and the computational complexity of converting unit 802 is significantly reduced.

On the other hand, be to reduce complexity, converting unit 802 (Look-up Table) mode of can tabling look-up in addition stores different resistance values R_AB, R_BC and length L [A, B], L[B, C] between relation; Simultaneously, the deviser can according to system requirements, determine the data number that this look-up table is included, with raising efficiency.

For instance, please refer to Fig. 9 A and Fig. 9 B, Fig. 9 A and Fig. 9 B are respectively embodiment of the invention conversion table 90,92 synoptic diagram, and its drafting mode is that the level of locating shaft P_AX and vertical moving range are divided into 10 rank, measure under the various mobile situations scope of resistance value R_AB and R_BC.Wherein, conversion table 90 is corresponding to the transformational relation of resistance value R_AB and length L [A, B], and then corresponding to the transformational relation of resistance value R_BC and length L [B, C], both all are stored in the converting unit 802 conversion table 92, for judging control signal DR_CMD's.Should be noted that Fig. 9 A and Fig. 9 B are in order to illustrate concept of the present invention, resistance value wherein only is an example, non-ly is limited to this.Simultaneously, for ease of explanation, summarize the also situation of the different intersection points of simplified illustration with terminal A, B to the resistance value of locating shaft P_AX in the conversion table 90,92.Secondly, because level and the vertical moving range of locating shaft P_AX are divided into 10 rank, therefore can suitably set an error burst.Take error burst as 15% as example, if a resistance value is p_rst in conversion table 90 or 92, a resistance value rx (R_AB or R_BC) who then judges when resistance detection unit 800 meets:

p_rst*(1-15％)＜rx＜p_rst*(1+15％)，

Then converting unit 802 can judge that resistance value rx is resistance value p_rst.

Conversion table 90,92 use-pattern are as follows.After resistance detection unit 800 detected resistance value R_AB, converting unit 802 can with its value according to aforesaid way comparison conversion table 90, be found out corresponding straight line or point (when the displacement of locating shaft P_AX equals the twice extreme value).Then, resistance detection unit 800 detects resistance value R_BC, and then converting unit 802 comparison conversion tables 92 are found out corresponding straight line or point (when the displacement of locating shaft P_AX equals the twice extreme value).At last, converting unit 802 both results of comparison can judge the mobile situation of locating shaft P_AX, and produce according to this control signal DR_CMD.

For instance, the initial position of supposing locating shaft P_AX is (6,6), if it is 400 ohm that resistance detection unit 800 detects resistance value R_AB, and resistance value R_BC is 1000 ohm, then converting unit 802 is first according to conversion table 90, judge the straight line (empty frame) shown in Figure 10 A, again according to conversion table 92, the position that to judge (3,3) corresponding point be locating shaft P_AX.In other words, locating shaft P_AX moves to (3,3) by initial position (6,6).Whereby, the control signal DR_CMD of converting unit 802 exportable correspondences.

In like manner, if it is 1000 ohm that resistance detection unit 800 detects resistance value R_AB, and resistance value R_BC is 400 ohm, then converting unit 802 is first according to conversion table 90, judge the straight line (empty frame) shown in Figure 11 A, again according to conversion table 92, the position that to judge (9,3) corresponding point be locating shaft P_AX.In other words, locating shaft P_AX moves to (9,3) by initial position (6,6).Whereby, the control signal DR_CMD of converting unit 802 exportable correspondences.

In addition, above stated specification is that the change with coordinate represents the content that control signal DR_CMD is possible, and in fact, the amplitude that also can change according to coordinate determines the meaning of control signal DR_CMD representative.For example, definable one " relatively pattern ", under this pattern, the object that indicator device 20 is controlled (such as the index of computer system or game) is according to the initial position of locating shaft P_AX and the gap of the position after moving, and decides mobile speed and direction.In addition, also definable one " absolute mode " corresponds to the object moving range that indicator device 20 is controlled with the each point in the moving range of locating shaft P_AX.Yet the content of control signal DR_CMD, function mode, form etc. all do not affect spirit of the present invention, and this area tool knows that usually the knowledgeable is when can suitably adjusting according to required.

In conventional art, the indicator device utilization is equal to the effect of switch corresponding to button or the trigger element generation of different directions, thereby can't accurately reflect user's Control the content.Under comparing, the present invention utilizes the length of rectangular conductive sheet MT_X, MT_Y and the relation between resistance value, judges the mobile situation of locating shaft P_AX, thereby can accurately judge user's Control the content.Should be noted that the modification of imitative this concept all should belong to category of the present invention, and applied field does not also affect the present invention, all can use indicator device 20 such as computer system, game machine, multimedia device, household electrical appliances or facility etc.In addition, elastic component EL can be object or the element of the reciprocal elastic force of tool such as spring, vapour-pressure type rubber ring, and is not limited to this.The length of rectangular conductive sheet MT_X, MT_Y is not limited to equate, can also be not isometric, as long as suitably adjust conversion table 90,92.In addition, the thickness of rectangular conductive sheet MT_X, MT_Y is preferably certain value, as long as but can guarantee that resistance value or certain electrical specification system and length are proportional or be particular kind of relationship, then its material, shape or even thickness also are not limited to any rule.For example, rectangular conductive sheet MT_X, MT_Y realize with the sheet metal of equal thickness, also can be that rigid plastic covers graphite outward, certainly are not limited to this.Moreover the assembling mode of housing also is not limited to the buckle mode, but the also locking mode such as periwinkle collecting silk.

In addition, control signal generation module 80 is connected to the method for terminal A, B, C can directly link terminal A, B, C by enameled wire, also can be by the shell fragment of rectangular conductive sheet MT_X, MT_Y bottom, indirectly is connected to terminal A, B, C.In addition, except connection end point A, B, C, other connected modes that can reflect length variations also can be utilized, for example, if rectangular conductive sheet MT_X, MT_Y and locating shaft P_AX are for being electrically connected, but the also resistance of measurement terminals A to locating shaft P_AX and locating shaft P_AX to terminal B then, and by suitable conversion regime, produce control signal DR_CMD.In this case, the connection of control signal generation module 80 and implementation also should correspondingly be revised, and these modifications should be the ability tool and know that usually the knowledgeable can finish easily with reference to above stated specification.

In indicator device 20, the shell fragment of rectangular conductive sheet MT_X, MT_Y bottom is the distance of keeping itself and base plate BS, in fact, also can increase above it shell fragment, as shown in figure 12, make itself and loam cake CS_UP keep fixing distance or pressure, to promote the assembling quality.

On the other hand, in previous example, all are the contact points when operating as the user with locating shaft loam cake P_CAP, and when practical application, the deviser can according to affiliated range of application, suitably adjust size or the external form of indicator device 20.For example, if be applied in the computer system, then can design the size of indicator device 20 for being fit to the user with the operation of finger driven mode, as shown in FIG. 13A; If be applied in the joystick, then can prolong locating shaft P_AX, so that the user can operate with the mode of holding, shown in Figure 13 B.

In addition, also indicator device 20 can be turned upside down, and just locating shaft loam cake P_CAP is fixed on the substrate, then the user operates in the mode of the base CS_DW of passing indicator device 20.Perhaps, locating shaft loam cake P_CAP is not fixed on the substrate, but loam cake CS_UP is fixed on the substrate, and locating shaft P_AX protrudes from base CS_DW simultaneously, for user's operation.

With regard to indicator device 20 inside, locating shaft P_AX is to keep perpendicular to base plate BS when mobile, for strengthening the convenience of its operation, can between base plate BS and locating shaft P_AX, increase the horizontal fixture of keeping its horizontal level, it can be the element that includes ball.Simultaneously, can further increase elastic component between annular fixing member FX and locating shaft P_AX, locating shaft P_AX is downward with compressing, makes the horizontal fixture base plate BS that can fit.Perhaps, can increase at base plate BS the hole of a suitable size, and horizontal fixture is located under this hole, locating shaft P_AX then passes hole, is connected with horizontal fixture; At this moment, elastic component newly-increased between annular fixing member FX and the locating shaft P_AX is in order to promote locating shaft P_AX, makes the horizontal fixture base plate BS that can fit.Certainly, the situation that the mode of newly-increased horizontal fixture also can cooperate indicator device 20 to turn upside down, then with the viewpoint of rectangular conductive sheet MT_X or MT_Y, the forced section that horizontal fixture and locating shaft P_AX bear external force can be (turn upside down and with the locating shaft P_AX that protrudes from base plate for controlling surface of contact) in the same side, or homonymy (normal running situation not, or turn upside down, and connect substrate under the locating shaft loam cake P_CAP, and with base plate for controlling surface of contact).

Locating shaft P_AX except keeping the move mode perpendicular to base plate BS, also can design its axle center be fixed on the base plate BS a bit, no longer keep fixing when namely moving.For example, can be at locating shaft P_AX with adding a central point fixture between base plate BS, such as elastic ring, locating shaft P_AX can be freely swung but do not break away from base plate BS.In this case, if annular fixing member FX still keeps the hard fixed form, then when locating shaft P_AX moves, may oppress rectangular conductive sheet MT_X, MT_Y.Therefore, can between annular fixing member FX and locating shaft P_AX, increase elastic component newly, when locating shaft P_AX is moved, still keep balance.Similarly, the situation that the mode of newly-increased central point fixture also can cooperate indicator device 20 to turn upside down, then with the viewpoint of rectangular conductive sheet MT_X or MT_Y, the forced section that central point fixture and locating shaft P_AX bear external force can be (to turn upside down in the same side same position, and connect substrate under the locating shaft loam cake P_CAP, and with base plate for controlling surface of contact) or diverse location (turn upside down, and with the locating shaft P_AX that protrudes from base plate for controlling surface of contact), or homonymy (normal running situation) not.

For rectangular conductive sheet MT_X, MT_Y, except fixing with shell fragment, can also increase Ka Gou at base plate BS, and change shell fragment into arrange in pairs or groups with Ka Gou fastener, such as iron plate or roller.
