< action of door switch >

Fig. 6 is the scheme drawing that is used to explain the action of door switch 10.

In addition, the corresponding relation of the structure schematically represented of the structure of said embodiment and Fig. 6 is described below.

Bullet push shaft 52a shown in Figure 2,52b and bullet push pedal 53a, 53b are equivalent to bullet pushed section 55a, 55b among Fig. 6.And bar 22 shown in Figure 4 and a pair of board 24 are equivalent to the bar unit 26 with bar 26a and detected portion 26b among Fig. 6.And spring 23 shown in Figure 4 is equivalent to the spring 27 among Fig. 6.And switch enclosure 30 shown in Figure 4 is equivalent to switch enclosure shown in Figure 6 36.And the pair of electrodes 25 among Fig. 4 is equivalent to the test section 28 among Fig. 6.

Fig. 6 (a) has represented that two 2 doors opening normally carry out the state (door 100a no show contract fully position, and the also state of no show contract fully position of door 100b) in the way of closing movement.

Fig. 6 (b) has represented that 2 doors normally carry out closing movement, and the state when all arriving the contract fully position.

Fig. 6 (c) has represented owing to the fault of device for opening/closing door 1 the only state of a side's of two 2 doors opening door 100a arrival contract fully position.

Fig. 6 (d) has represented owing to the fault of device for opening/closing door 1 the only state of the opposing party's of two 2 doors opening door 100b arrival contract fully position.

When shown in Fig. 6 (a), 2 doors are in when the position of predetermined distance is only left in the contract fully position, are not connected on the door switch 10 with respect to door 100a, bullet pushed section 55a, 55b that 100b is fixing respectively.Under this state, test section 28 separates under the effect of the bullet thrust of spring 27 with detected portion 26b.

When

door

100a, 100b from the state shown in Fig. 6 (a) further when closing direction moves; With respect to fixing 2 of this 100a, 100b play pushed section 55a, 55b move to approximating direction (the arrow X2 direction among Fig. 6), this bullet pushed section 55a, 55b almost are connected on the front end and switch enclosure 36 of bar 26a (in Fig. 6 (a), representing with long and two-short dash line) simultaneously.

And then, moving to closing direction through

door

100a, 100b, bar unit 26 overcomes the bullet thrust of spring 27 and moves (with reference to Fig. 6 (b)) to the identical direction of moving direction with this bullet pushed section 55a under the effect from the bullet thrust that plays pushed section 55a.

On the other hand, switch enclosure 36 overcomes the bullet thrust of spring 27 and goes up mobile at slide rail 40 (omitting among Fig. 6) to the direction identical with the moving direction of this bullets pushed section 55b under the effect from the bullet thrust that plays pushed section 55b.

That is, move to closing direction through

door

100a, 100b, spring 27 shrinks the ground distortion, and the interval that the relative position relation of this bar unit 26 and switch enclosure 36 is varied to detected portion 26b and test section 28 narrows down.

When shown in Fig. 6 (b), when both sides'

door

100a, 100b arrival contract fully position, the detected portion 26b of bar unit 26 is connected on the test section 28.And when detected portion 26b is connected to 28 last times of test section, detection signal is to the control part output of device for opening/closing door 1.This control part decision gate when receiving this detection signal is closed fully, is used in the blocking device action that the constraint door moves towards opening direction.Particularly, for example, screw actuator encourages because of detection signal, is arranged on locking bar card on this screw actuator and ends at

door

100a, 100b upward, locks this 100a, 100b moves to opening direction.In addition, also can stop this moment through the output of electro-motor that control part is used in the miniature gears rotation of device for opening/closing door 1.

When shown in Fig. 6 (c), under the situation that the closing movement of

door

100a, 100b door 100b when closing direction moves stops, having only a 100a to move to closing direction, the bullet pushed section 55a bullet that door switch 10 only is fixed on this 100a pushes away.That is, this moment only bar unit 26 directly pushed away by bullet.

Like this, because only bar unit 26 is directly pushed away by bullet, switch enclosure 36 moves to the identical direction of moving direction with bullet pushed section 55a along slide rail 40.At this moment, spring 27 does not almost shrink, and detected portion 26b compares with the interval under the state shown in Fig. 6 (a) almost with the interval of test section 28 and do not change.

So, under the situation that door 100b does not close fully, can be from door switch 10 output detection signals.

Equally, when shown in Fig. 6 (d), under the situation that the closing movement of

door

100a, 100b door 100a when closing direction moves stops, having only a 100b to move to closing direction, the bullet pushed section 55b bullet that door switch 10 only is fixed on this 100b pushes away.That is, this moment only switch enclosure 36 directly pushed away by bullet.

Like this, because only switch enclosure 36 is directly pushed away by bullet, switch enclosure 36 moves to the identical direction of moving direction with bullet pushed section 55b along slide rail 40 with bar unit 26.At this moment, spring 27 does not almost shrink, and detected portion 26b compares with the interval under the state shown in Fig. 6 (a) almost with the interval of test section 28 and do not change.

So, under the situation that door 100a does not close fully, can be from door switch 10 output detection signals.

< effect of embodiment >

(the 1st variation)

Said embodiment can be out of shape to implement as following.

Fig. 7 is the scheme drawing of action that is used to explain the 1st variation of said embodiment.The related device for opening/closing door of the 1st variation is different with said embodiment on the different this point of structure of door switch.Therefore, the structure of door switch only is described, is omitted to other structure.In addition, on the parts identical with said embodiment, giving identical Reference numeral describes.

As shown in Figure 7, the door switch 11 of the 1st variation possesses: switch enclosure 61; Base end side is configured in 2

bars

62,63 that this switch enclosure 61 is provided with interiorly; Be configured in the

spring

64,65 between the inside face of cardinal extremity and switch enclosure 61 of this

bar

62,63; Be fixed on the magnet 66 on a side the bar 62; And be fixed on the Magnetic Sensor 67 on the opposing party's the bar 63.

In addition, on the switching direction of door, with the position configuration of

bar

62,63 subtends the pushed section 56a of bullet, 56b are arranged respectively.Bullet pushed

section

56a, 56b link to each other with

door

100a, 100b respectively, along with moving of

door

100a, 100b.

Switch enclosure 61 is directly fixing with respect to substrate 9.That is, switch enclosure 61 is fixed into and can not relatively moves with respect to vehicle body.

It is outstanding from switch enclosure 61 that bar 62 is configured to its front end, and cardinal extremity is positioned at switch enclosure 61.This bar 62 is set as with respect to switch enclosure 61 freely advances and retreat in the axial direction.In addition, the advance and retreat direction of bar 62 is parallel with the switching direction of door.

Between bar 62 and switch enclosure 61, dispose spring 64.This spring 64 is from the distolateral forward bullet push rod 62 of base end side.

And, be fixed with magnet 66 at the axial pars intermedia of bar 62.Be fixed on the bar 62 to this magnet 66 and bar 63 side subtends.

And constitute bullet pushed section 56a and move to closing direction, thereby the front end of bar 62 is pushed away by this bullet pushed section 56a bullet along with the closing movement of door 100a.

Bar 63 be configured to its front end from switch enclosure 61 to outstanding with the opposite sense of bar 62, its cardinal extremity is positioned at switch enclosure 61.This bar 63 is set as with respect to switch enclosure 61 freely advances and retreat in the axial direction.In addition, the advance and retreat direction of bar 63 is parallel with the switching direction of door.

And bar 63 is disposed in the position that the direction that is orthogonal to substrate 9 (the paper depth direction of Fig. 7) goes up and bar 62 is roughly the same.That is, observe abreast with vertical direction,

bar

62,63 is configured to the center shaft of bar 62 and the center shaft of bar 63 is located along the same line.

Between bar 63 and switch enclosure 61, dispose spring 65.This spring 65 from base end side towards front bullet push rod 63.

And axial pars intermedia is fixed with Magnetic Sensor 67 on bar 63.Be fixed on the bar 63 to this Magnetic Sensor 67 and bar 62 side subtends.

And constitute through playing pushed section 56b and move to closing direction along with the closing movement of door 100b, the front end of bar 63 is pushed away by this bullet pushed section 56b bullet.

Shown in Fig. 7 (a); Under the state that bar 62,63 is not all pushed away by bullet pushed

section

56a, 56b bullet; The effect that bar 62 remains on the bullet thrust of spring 64 is moved to the state that plays pushed section 56a side, and bar 63 keeps under the effect of the bullet thrust of spring 65 to playing pushed section 56b side shifting.Therefore, magnet 66 remains on not on the position with Magnetic Sensor 67 subtends.

When

door

100a, 100b continue when closing direction moves; Playing pushed section 56a is connected on the bar 62; Playing pushed section 56b is connected on the bar 63; Bar 62 overcomes the bullet thrust of spring 64 to playing pushed section 56b side shifting under the effect of the bullet thrust that plays pushed section 56a, bar 63 overcomes the bullet thrust of spring 65 to playing pushed section 56a side shifting under the effect of the bullet thrust that plays pushed section 56b.

And shown in Fig. 7 (b), when 2

door

100a, 100b normally carry out closing movement, and when all arriving the contract fully position, magnet 66 and Magnetic Sensor 67 subtends.That is, make magnet 66 near Magnetic Sensor 67.

At this, Magnetic Sensor 67 the specialized range detection range of Magnetic Sensor 67 (below be called) internal magnet 66 near the time detect the magnetic of magnet, with respect to the control part output detection signal of device for opening/closing door.And in this variation, the interval of

bar

62,63 is adjusted to the detection range that magnet 66 only gets into Magnetic Sensor 67 at magnet 66 during with Magnetic Sensor 67 subtends (, magnet 66 near Magnetic Sensor 67 time).

Therefore, only at 2 door 100a, when 100b all arrives the contract fully position, Magnetic Sensor 67 output detection signals.

Therefore, shown in Fig. 6 (c), in the fault because of device for opening/closing door 1, only a side door 100a arrives the contract fully position, and under the state that the opposing party's door 100b stops halfway, Magnetic Sensor 67 and magnet 66 is subtend not each other, not from Magnetic Sensor 67 output detection signals.

Equally, shown in Fig. 6 (d), in the fault because of device for opening/closing door 1, only door 100b arrives the contract fully position, and under the state that door 100a stops halfway, Magnetic Sensor 67 and magnet 66 is also subtend not each other, not from Magnetic Sensor 67 output detection signals.

(effect of the 1st variation)

As discussed above, the related door switch 11 of the 1st variation possesses: can be provided with respect to substrate 9 (vehicle body), at the bar 62 (the 1st effector) that when move the contract fully position, pushed away by bullet of a side door 100a with relatively moving; The bar 63 (the 2nd effector) that when move the contract fully position, is pushed away by bullet at the opposing party's a 100b can be set with respect to substrate 9 and bar 62 with relatively moving; When the relative position of bar 62 and bar 63 becomes the relative position of regulation, the Magnetic Sensor 67 (detection components) of magnet 66 output detection signal near in the detection range time; And bullet push rod 62 makes the relative position that plays push rod 62 and bar 63 not become the spring 64,65 (bullet pushes away assembly) of the relative position (magnet 66 gets into the interior relative positions of Magnetic Sensors 67 detection ranges) of said regulation with bar 63.At this; The relative position of the said regulation bullet thrust that to be bar 62 overcome spring 64,65 with bar 63 is set at two last bullet pushed section 56a, 56b bullets of opening of 2 door 100a, 100b and pushes away, and the relative position of these 2 door 100a, the bar when 100b all moves to the contract fully position 62 and bar 63.

According to this structure; Side's in 2

door

100a, 100b door moves to the contract fully position; Under the situation of the opposing party's door no show contract fully position, because under the effect of the bullet thrust of

spring

64,65, bar 62 and the relative position of bar 63 do not become the relative position of said regulation; Magnet 66 does not get in the detection range of Magnetic Sensor 67, therefore can be from Magnetic Sensor 67 with respect to the control part output detection signal.

The quantity that so, needn't increase switch promptly can detect two

door

(the 2nd variation)

Said embodiment can be out of shape to implement as following.

Fig. 8 and Fig. 9 are the scheme drawings of action that is used to explain the 2nd variation of said embodiment.The related device for opening/closing door of the 2nd variation is different with said embodiment on the different this point of structure of door switch.Therefore, the structure of door switch only is described, is omitted to other structure.In addition, on the parts identical with said embodiment, giving identical Reference numeral describes.

As shown in Figure 8, the door switch 12 of the 2nd variation has: the axle 71 that is fixed on the substrate 9 and extends with respect to these substrate 9 quadrature ground; Dispose abreast with substrate 9, and be set as the 1st rotatable parts 72 of the quadrant parts that freely rotate around axle 71; Be provided with overlappingly with the 1st rotatable parts 72, and be set as the 2nd rotatable parts 73 of the long slab shape that can freely rotate around axle 71; Be arranged on the spring 74 between the 1st rotatable parts 72 and the 2nd rotatable parts 73; Be arranged on the Magnetic Sensor 75 on the 1st rotatable parts 72; Be arranged on the magnet 76 on the 2nd rotatable parts 73; Be fixed on the substrate 9 and limit the 1st retainer 77 of the rotation (rotation of the arrow R1 direction among Fig. 8) of the 1st rotatable parts 72; And be fixed on the substrate 9 and limit the 2nd retainer 78 of the rotation (rotation of the arrow R2 direction among Fig. 8) of the 2nd rotatable parts 73.

In addition, be fixed with shaft-like bullet pushed section 57a, the 57b that extends abreast with the switching direction of door via

support component

51a, 51b respectively in that

door

100a, 100b are last.

Near the 1st rotatable parts 72 portion center of arc can link around axle 71 freely to rotate.And near the circular arc edge portion of the 1st rotatable parts 72, and near the rectilinear edge portion that is positioned at the linear edge portion opposition side of 77 butts of the 1st retainer, be fixed with Magnetic Sensor 75.

The 2nd rotatable parts 73 are radius long plate shape parts about equally of length and the 1st rotatable parts 72, and near the portion of an end links around axle 71 freely to rotate, and near the portion of the other end is fixed with magnet 76.And the 2nd rotatable parts 73 constitute from axle 71 to magnet 76 distance and 75 distance equates from axle 71 to Magnetic Sensor.

Spring 74 be with an end be fixed near the rectilinear edge portion that is connected on the 1st rotatable parts 72 on the 1st retainer 77, in the substantial middle portion of the 1st rotatable parts 72 radial directions.And spring 74 is fixed on the other end in the substantial middle portion of length direction of the 2nd rotatable parts 73.And spring 74 bullets push away the 1st rotatable parts 72, make its direction around axle 71 (among Fig. 8 around the C.C.W. direction.R1 representes with arrow) rotate, and bullet pushes away the 2nd rotatable parts 73, make its to the opposite sense of this direction (among Fig. 8 around the clws direction.R2 representes with arrow) rotate around axle 71.

Therefore; Under the situation that external force (spring 74 beyond power) does not act on respect to the 1st rotatable parts 72 and the 2nd rotatable parts 73; Shown in Fig. 8 (a), the 1st rotatable parts 72 keep the state on the 1st retainer 77 that is connected to, and the 2nd rotatable parts 73 keep the state on the 2nd retainer 78 that is connected to.

Under this state, on the direction of axle 71, Magnetic Sensor 75 is separated from one another with magnet 76.

And move to closing direction along with the closing movement of

door

100a, 100b through bullet pushed

section

57a, 57b, shown in Fig. 8 (b), bullet pushed

section

57a, 57b are connected to respectively in the edge portion of the 1st rotatable parts 72 and the 2nd rotatable parts 73.Particularly, playing pushed section 57a is connected on the 1st rotatable parts 72 in the edge portion that radial alignment is extended.And, play pushed section 57b and be connected on the 2nd rotatable parts 73 in the alongst linearly extended edge portion.

And then, moving to closing direction through bullet pushed

section

57a, 57b, the 1st rotatable parts 72 are played pushed section 57a bullets and are pushed away, and the bullet thrust that overcomes spring 74 is rotated around axle 71 to the direction of leaving the 1st retainer 77 (the arrow R2 direction among Fig. 8).

And the 2nd rotatable parts 73 are played pushed section 57b bullet and are pushed away, and the bullet thrust that overcomes spring 74 is rotated around axle 71 to the direction of leaving the 2nd retainer 78 (the arrow R1 direction among Fig. 8).

That is, move to closing direction through bullet pushed

section

57a, 57b, Magnetic Sensor 75 moves to approximating direction with magnet 76.

And when 2

door

100a, 100b normally carried out closing movement and all arrive the contract fully position, shown in Fig. 8 (c), Magnetic Sensor 75 was overlapping with magnet 76.That is, magnet 76 is near Magnetic Sensor 75.

At this, Magnetic Sensor 75 the scope detection range of Magnetic Sensor 75 (below the be called) internal magnet 76 of regulation near the time detect the magnetic of magnet, with respect to the control part output detection signal of device for opening/closing door.And in this variation; The interval of the 1st rotatable parts 72 and the 2nd rotatable parts 73 (interval on the direction parallel) with axle 71 only be adjusted to when magnet 76 and Magnetic Sensor 75 are overlapping (; Magnet 76 is during near Magnetic Sensor 75), magnet 76 enters in the detection range of Magnetic Sensor 75.

Therefore, only at 2 door 100a, when 100b all arrives the contract fully position, Magnetic Sensor 75 output detection signals.

Therefore, shown in Fig. 9 (a), in the fault owing to device for opening/closing door 1, only a side door 100a arrives the contract fully position, and under the state that the opposing party's door 100b stops halfway, Magnetic Sensor 75 is not overlapping with magnet 76, not from Magnetic Sensor 75 output detection signals.

Equally, shown in Fig. 9 (b), in fault owing to device for opening/closing door 1; Only a side door 100b arrives the contract fully position; And under the state that the opposing party's door 100a stops halfway, Magnetic Sensor 75 is not overlapping with magnet 76 yet, not from Magnetic Sensor 75 output detection signals.

(effect of the 2nd variation)

(1) that kind as described above, the related door switch 12 of the 2nd variation possesses: the 1st rotatable parts 72 (the 1st effector) that when move the contract fully position, pushed away by bullet at a side door 100a can be set with respect to substrate 9 (vehicle body) with relatively rotating; Can change ground relatively with respect to substrate 9 and the 1st rotatable parts 72 and be provided with, the 2nd rotatable parts 73 (the 2nd effector) that when move the contract fully position, pushed away at the opposing party's door 100b by bullet; Become the relative position of regulation at the relative position of the 1st rotatable parts 72 and the 2nd rotatable parts 73, the Magnetic Sensor 75 (detection components) of magnet 76 output detection signal near in the detection range time; And bullet pushes away the 1st rotatable parts 72 and the 2nd rotatable parts 73, makes the relative position of the 1st rotatable parts 72 and the 2nd rotatable parts 73 not become the spring 74 (bullet pushes away assembly) of the relative position (magnet 76 gets into the positions in the detection range of Magnetic Sensors 75) of regulation.At this; The relative position of said regulation is that bullet thrust that the 1st rotatable parts 72 and the 2nd rotatable parts 73 overcome spring 74 is set at two last bullet pushed section 57a, 57b bullets of opening of 2 door 100a, 100b and pushes away, and these 2 door 100a, the 1st rotatable parts 72 when 100b all moves to the contract fully position and the relative position of the 2nd rotatable parts 73.

door

100a, 100b; Under the situation of the opposing party's door no show contract fully position, because under the effect of the bullet thrust of spring 74, the relative position of the 1st rotatable parts 72 and the 2nd rotatable parts 73 does not become the relative position of said regulation; Magnet 76 does not get in the detection range of Magnetic Sensor 75, therefore can be from Magnetic Sensor 75 with respect to the control part output detection signal.

The quantity that so, needn't increase switch promptly can detect two

door

(2) in door switch 12, the 1st rotatable parts 72 and the 2nd rotatable parts 73 are set as and wind axle 71 (turning cylinders) fixing with respect to substrate 9 and freely rotates, and axle 71 is with respect to flat door 100a, upward extension of direction (Width of vehicle) that 100b is vertical.

And the 1st rotatable parts 72 and the 2nd rotatable parts 73 form tabular, and be configured to the axle 71 parallel directions be thickness direction.So, can reduce the shared space of on the Width of vehicle door switch 12.

(3) in door switch 12; When Magnetic Sensor 75 on being arranged on the 1st rotatable parts 72 (the 1st test section) and the position that is arranged on magnet 76 (the 2nd test section) on the 2nd rotatable parts 73 and becomes regulation concern; Be magnet 76 when entering in the detection range of Magnetic Sensor 75, these Magnetic Sensor 75 output detection signals.This Magnetic Sensor 75 is configured on the 1st rotatable parts 72 than plays position that pushed section 57a bullet pushes away on the position of axle 71.And magnet 76 is configured on the 2nd rotatable parts 73 than plays position that pushed section 57a bullet pushes away on the position of axle 71.

According to this structure, to compare towards the amount of movement of closing direction (amount of movement after being connected on the 1st rotatable parts 72 and the 2nd rotatable parts 73 certainly) with

door

100a, 100b, the variable quantity of the relative position between Magnetic Sensor 75 and the magnet 76 increases.So, the precision of sensor be can improve and the door 100a that is closed in the action, the thin objects that 100b clamps detected.That is, can prevent to clip between door 100a, the 100b in closing movement foreign matter, door 100a through easy structure, when 100b does not close fully, output detects a 100a, the buttoned-up detection signal of 100b by error.

(the 3rd variation)

Be not limited in the 2nd variation that kind is provided with spring 74 between the 1st rotatable parts 72 and the 2nd rotatable parts 73 situation, also can constitute as illustrated in fig. 10.

In this structure, near the 1st retainer 77 of substrate 9, be fixed with from the 1st outstanding spring maintaining part 81 of substrate 9.And, near the 2nd retainer 78, be fixed with the 2nd spring maintaining part 82 of giving prominence to from substrate 9.And between the 1st spring maintaining part 81 and the 1st rotatable parts 72, be provided with the 1st spring 83.The 1st spring 83 is drawn into the 1st rotatable parts 72 and makes the 1st rotatable parts 72 near the 1st retainer 77.And, between the 2nd spring maintaining part 82 and the 2nd rotatable parts 73, be provided with the 2nd spring 84.The 2nd spring 84 is drawn into the 2nd rotatable parts 73 and makes the 2nd rotatable parts 73 near the 2nd retainer 78.

Therefore; Under the situation that external force (spring 74 beyond power) does not act on respect to the 1st rotatable parts 72 and the 2nd rotatable parts 73; Shown in Figure 10 (a), the 1st rotatable parts 72 keep the state on the 1st retainer 77 that is connected to, and the 2nd rotatable parts 73 keep the state on the 2nd retainer 78 that is connected to.

And when 2 doors all arrived the contract fully position, shown in Figure 10 (b), Magnetic Sensor 75 was overlapping with magnet 76.

Like this, according to the structure of Figure 10 record, can be only when 2 doors all arrive the contract fully position from door switch 12 output detection signals.

(the 4th variation)

Be not limited in such the 1st rotatable parts 72 of the 3rd variation and form fan-shaped situation, for example, also can be in as forming L font or V-shape as that kind shown in the 1st rotatable parts 72 ' among Figure 11.In this case, the 72 ' lightweight of the 1st rotatable parts can be made, and the requisite space that the 1st rotatable parts 72 ' rotate can be reduced to be used for.

And; The turning cylinder that is not limited in such the 1st rotatable parts 72 of said the 2nd～4 variation and the turning cylinder of the 2nd rotatable parts 73 are the situation of identical turning cylinder (spool 71); Also can the turning cylinder of the 1st rotatable parts 72 turning cylinder with the 2nd rotatable parts 73 be separated, be separately positioned on different positions.
