The above-described door opening and closing device is configured such that two doors of the double-open type are mechanically interlocked to open and close. Therefore, when one of the double-open type door positions is in the fully closed position, normally, the other door is also in the fully closed position. Therefore, by the above-mentioned door closing switch, one of the two doors of the double opening type can be judged. Whether it is in the fully closed position.

However, the possibility of malfunctioning the double-opening door interlocking mechanism is not zero. Therefore, even when the door interlocking mechanism fails, it is possible to reliably detect whether the double-opening door is in the fully closed position of the railway vehicle door switch.

For this reason, it is conceivable to provide two of the above-described door closing switches corresponding to the double-opening doors, but once according to this method, the number of switches is increased, and the number of electronic components is increased, which may cause an increase in the overall failure rate of the system. Also, the increase in the number of parts will increase the cost. In addition, instead of fixing the door closing switch to the vehicle body, it is conceivable to install it on one door and the other door to operate the door closing switch. However, the wiring of the door closing and closing will have the same degree of movement as the opening and closing stroke. It is easy to cause the disconnection of the wiring, and it is difficult to detect whether the double-opening door is in the fully closed position. And because the durability of the wiring is more required, the cost is also increased.

In view of the above-described circumstances, the present invention provides a door switch for a railway vehicle that can more reliably detect whether a double-open door is a fully closed position and a door opening and closing device for a railway vehicle having the same without increasing the number of switches. for purpose.

A first feature of the railway vehicle door switch according to the present invention is a railway vehicle door switch provided in a railway vehicle having a double-open type door, and is provided to be relatively movable in parallel with the opening and closing direction of the door of the vehicle body. The first driven portion that is pushed when the door moves toward the fully closed position; a second receiving portion that is relatively movable when the vehicle body and the first driven portion are relatively moved, and the other door is moved toward the fully closed position; and a relative position between the first driven portion and the second driven portion is formed to be a predetermined relative position a position detecting means for outputting a detection signal; and an elastic member disposed between the first receiving portion and the second receiving portion; wherein the first receiving portion and the elastic member and the detecting means constitute a limit switch The limit switch is provided to be movable in parallel with the forward direction of the second driven portion with respect to the vehicle body, and one of the doors is pushed by the first driven portion, and the other door is The second receiving portion is pushed by the second receiving portion to move against the elastic force of the elastic member with respect to the second receiving portion, and the first door is configured to be the first one when the two doors reach the fully closed position. The driven portion moves the predetermined amount by the second driven portion.

According to this configuration, when only one of the doors is moved to the fully closed position and the other door does not reach the fully closed position, the first driven portion and the second driven portion are not moved by the spring force of the spring pushing means. The relative positions of the portions form a predetermined relative position, so that no detection signal is output from the detecting means.

Thereby, the number of switches is not increased, and it is more sure to detect whether the double-opening door is in the fully closed position.

Further, according to this configuration, it is possible to more reliably detect whether or not the double-open type door is located by using the limit switch that outputs the detection signal when the first driven portion is moved by the predetermined amount by the elastic force of the elastic member with respect to the second driven portion. The composition of the closed position. Therefore, for example, it is also possible to use the widely used ones in the past. Highly reliable limit switches ensure the reliability of door switches for railway vehicles.

Further, a second feature of the railway vehicle door switch according to the present invention includes: a substrate constituting a part of the vehicle; a track that is in contact with the substrate and fixed in parallel with the opening and closing direction of the door; and along the track The guide member is engaged with the rail by being movable in parallel with the opening and closing direction of the door, and is fixed to the guide member of the second driven portion.

According to this configuration, the door switch for the railway vehicle can be disposed by a space extending in parallel with the opening and closing direction of the door.

Further, a third feature of the railway vehicle door switch according to the present invention is a railway vehicle door switch provided in a railway vehicle having a double-open type door, and is provided to be relatively movable to the vehicle body, and one door is fully closed. a first driven portion that is pushed when the position is moved; a second driven portion that is relatively movable when the vehicle body and the first driven portion are relatively moved, and the other door is moved toward the fully closed position; the first driven portion a detecting means for outputting a detection signal when the relative position of the second receiving portion is formed at a predetermined relative position; and an elastic member provided between the first receiving portion and the second receiving portion, the first receiving portion and The second driven portion is rotatably provided around a rotary shaft fixed to the vehicle body, and the rotary shaft extends in a vertical direction of the flat door, and one of the doors is pushed by the first driven portion. And the other door is pushed by the second driven portion, whereby the first driven portion moves against the elastic force of the elastic member with respect to the second driven portion. Said door 2 reaches the fully closed position are configured by the first movable portion and the movable portion by the relative position becomes the predetermined second relative position.

According to this configuration, the first receiving portion and the second receiving portion are formed to have a thin thickness in a direction parallel to the rotation axis, and space saving can be easily achieved.

According to a fourth aspect of the present invention, in the railway vehicle door switch, the detecting means forms a predetermined positional relationship between the first detecting portion provided in the first receiving portion and the second detecting portion provided in the second receiving portion. Output In the detection signal, the first detecting unit is disposed at a position farther from the rotation axis of the first driven portion than the position at which the door is pushed to the first receiving portion, and the second detecting unit is at the second portion The driven portion is disposed at a position farther from the rotation axis of the second driven portion than the position at which the door is pushed by the door.

According to this configuration, the amount of change in the relative position between the first detecting unit and the second detecting unit is increased in comparison with the amount of movement in the closing direction of the door. Thereby, it is possible to easily prevent the output of the detection signal in which the door is closed due to an erroneous detection when the door is not completely closed due to the foreign matter being caught between the doors during the closing operation.

Further, the door opening and closing device for a railway vehicle according to the present invention is a door opening and closing device for a railway vehicle for opening and closing a double opening type, and includes a door for a railway vehicle having at least one of the features of the first to fourth aspects. And a switch for receiving a detection signal outputted from the detection means, wherein the control unit drives the lock device for locking the door and the drive output for opening and closing the door based on the detection signal.

According to this configuration, it is possible to surely detect whether or not the double-open type door is in the fully closed position, and the detection signal outputted by the detecting means can be used for the locking of the door or the driving control of the door.

Thereby, it is possible to prevent the door from being locked due to an error when the door does not reach the fully closed position. It can prevent the drive output for opening and closing the door due to an error when the door does not reach the fully closed position.

According to the railway vehicle door switch of the present invention and the railway vehicle door opening and closing device provided with the door switch, it is not necessary to increase the number of switches, and it is possible to more reliably detect whether the double-open type door is in the fully closed position.

Hereinafter, the form for carrying out the invention will be described with reference to the drawings.

That is, the door switch 10 is disposed above the door edge of the doors 100a, 100b in the fully closed position.

<Configuration of door switch>

Fig. 2 is an enlarged view showing the vicinity of the door switch 10 provided in the door opening and closing device 1 in Fig. 1 . Further, Fig. 3 is a view showing the door switch 10 shown in Fig. 2 from the vehicle front side (the pad 35 side) parallel to the opening and closing direction of the doors 100a and 100b. Further, Fig. 4(a) is a view showing the door switch 10 on the side opposite to the substrate 9. In the fourth (a) diagram, as the internal structure of the limit switch 20 is understood, a part of the representation of the main body casing 21 of the limit switch 20 is omitted. Further, Fig. 4(b) is a view showing the door switch 10 shown in Fig. 4(a) from the direction of the arrow A.

As shown in FIG. 2, the door switch 10 includes a limit switch 20 and a box type switch case 30 in which the limit switch 20 is housed.

As shown in FIG. 3, the switch box 30 is fixed to the substrate 9 via the rail 40.

As shown in FIGS. 3 and 4, the rail 40 is fixed to the substrate 9 and extends in parallel in the opening and closing direction of the doors 100a and 100b. Further, the bottom plate 31 of the switch case 30 is fixed with a guide member 32 that engages with the rail 40. The introduction The guide member 32 is movable along the slide rail 40 in a state of being engaged with the slide rail 40. Thereby, the switch case 30 can be moved along the rail 40 in parallel with the opening and closing directions of the doors 100a and 100b. Further, in the present embodiment, the maintenance of the limit switch 20 can be easily performed by opening the opposite side of the bottom plate 31 of the switch case 30.

As shown in FIG. 4, the limit switch 20 is provided with a main body case 21 in which a detecting mechanism can be housed, and a rod 22 projecting from the main body case 21. The rod 22 has its front end side and the base end side inserted into the through holes 21a and 21b formed in the main body case 21, and is held in the main body case 21 so as to be movable in the axial direction of the main body case 21. Further, the tip end of the rod 22 is pressed into the main body casing 21 by a predetermined amount, thereby constituting an output detection signal (Fig. 4 shows a state in which the rod 22 is pressed in. For the state in which the rod 22 is not pressed, see the fifth. Figure).

Specifically, the rod 22 has an enlarged diameter portion 22a that is expanded in diameter in the axially intermediate portion as compared with the distal end side and the proximal end side. Further, a spring 23 is disposed between the enlarged diameter portion 22a and the main body case 21. The spring 23 is disposed around the shaft on the proximal end side of the rod 22, and the enlarged diameter portion 22a is pushed toward the distal end side in the axial direction. Further, a pair of plate portions 24 are extended from the enlarged diameter portion 22a in a direction orthogonal to the axial direction. The main body casing 21 is provided with a space in which the plate portion 24 can be moved in a predetermined amount toward the axial direction of the rod 22. Further, the pair of plate portions 24 are provided with a pair of electrodes 25 at positions facing the proximal end side of the rod 22 in the axial direction. When the pair of plate portions 24 abut against the pair of electrodes 25, the pair of electrodes 25 are electrically connected to form a predetermined circuit output detection signal.

Thereby, the front end of the rod 22 is pushed toward the axial direction, so that the rod 22 is moved toward the axial base end side by a predetermined amount against the elastic thrust of the spring 23, so that the same The pair of plate portions 24 abut against the pair of electrodes 25, and output a detection signal to the control portion of the door opening and closing device 1.

Further, the door opening and closing device 1 is provided with a control unit including a microcomputer such as a CPU and a memory. Further, the detection signal output from the limit switch 20 is input to the control unit via the wiring connector 37 and a wiring (not shown). The control unit controls the opening and closing mechanism of the door and the locking device of the door based on the detection signal.

The limit switch 20 penetrates the front end of the rod 22 through the through hole 33a formed in the side wall 33 of the switch case 30, and is disposed in the switch case 30 so as to protrude outside the switch case 30. The limit switch 20 is fixed to the bottom plate 31 of the switch case 30 by a bolt or the like. Here, the limit switch 20 is configured such that the shaft of the rod 22 extends parallel to the rail 40.

Further, the switch case 30 is positioned on the outer side of the side wall 34 on the side opposite to the side wall 33 of the through hole 33a through which the rod 22 is formed, and a disc-shaped pad formed of a member having a lower rigidity than the side wall 34 is fixed. 35. Further, in the present embodiment, the spacer 35 made of rubber is formed to prevent excessive impact on the door switch 10 due to the contact of the door. However, the present embodiment also includes a buffer mechanism to be described later. It may be a metal, and may have no gasket as long as it does not cause deformation such as deformation of the side wall 34.

As shown in Fig. 2, support members 51a and 51b extending upward are fixed to the vicinity of the door edge of the upper end portions of the pair of doors 100a and 100b, respectively. The support members 51a and 51b are attached with pinion shafts 52a and 52b extending in parallel with the opening and closing directions of the doors 100a and 100b.

It is shown from the door switch 10 that the pinch shaft 52a provided on the door 100a on the front end side of the rod 22 is disposed substantially coaxially with the rod 22. Further, a tip end of the pinion shaft 52a (an end portion facing the tip end of the rod 22) is fixed to a poppet 53a orthogonal to the pinion shaft 52a. When the door 100a is moved in the closing direction, the front end of the push rod 22 that can be pushed by the poppet 53a is formed.

It is shown from the door switch 10 that the pinch shaft 52b provided on the door 100b on the side of the pad 35 is disposed substantially coaxially with the central axis of the disc-shaped pad 35. Further, a tip end of the pinion shaft 52b (an end portion opposed to the pad 35) is fixed to a poppet 53b orthogonal to the pinion shaft 52b. When the door 100b is moved in the closing direction, the pad 35 can be pushed by the poppet 53b.

Further, the pinch shafts 52a, 52b are respectively provided with a damper mechanism. These damper mechanisms have a function of mitigating an impact when the door moves toward the closing direction by the urging plates 53a, 53b abutting against the front end of the rod 22 or the gasket 35. In this embodiment, although the damper mechanism is constituted by a spring, it is possible to alleviate excessive impact on the door switch 10 with the abutment of the door, whether it is a combination of a spring and a damper, or a rubber or the like. The composition can be.

<Action of the door switch>

Fig. 6 is a schematic view for explaining the operation of the door switch 10.

Further, the correspondence between the configuration of the above embodiment and the configuration shown in the sixth mode is as follows.

The pinch shafts 52a, 52b and the pedals 53a, 53b shown in Fig. 2 are Corresponding to the spring pushing portions 55a and 55b of Fig. 6. Further, the rod 22 and the pair of plate portions 24 shown in Fig. 4 correspond to the rod unit 26 having the rod 26a and the detected portion 26b of Fig. 6 . Further, the spring 23 shown in Fig. 4 is a spring 27 corresponding to Fig. 6. Further, the switch case 30 shown in Fig. 4 corresponds to the switch case 36 shown in Fig. 6. Further, the pair of electrodes 25 in Fig. 4 corresponds to the detecting portion 28 of Fig. 6.

Fig. 6(a) is a view showing a state in which the two doors of the double-open type are normally closed (the door 100a has not reached the fully closed position, and the door 100b has not reached the fully closed position).

Fig. 6(b) is a view showing a state in which the two doors are normally closed, and all of them reach the fully closed position.

The sixth figure (c) shows a state in which only one of the two doors of the double-open type door reaches the fully closed position due to the failure of the door opening and closing device 1.

Fig. 6(d) is a view showing a state in which only the other door 100b of the two doors of the double-open type reaches the fully closed position due to the failure of the door opening and closing device 1.

As shown in Fig. 6(a), when the two door positions are separated from the fully closed position by a predetermined distance, the respective push portions 55a and 55b which are fixed to the doors 100a and 100b are not in contact with the door switch 10. In this state, the detecting portion 28 is separated from the detected portion 26b by the spring force of the spring 27.

When the doors 100a and 100b are moved in the closing direction from the state shown in Fig. 6(a), the two projecting portions 55a and 55b fixed to the doors 100a and 100b are oriented in the direction in which they approach each other (6th). Figure arrow X2 In the direction), the projecting portions 55a and 55b abut the distal end of the rod 26a and the switch case 36 substantially at the same time (indicated by a two-dot chain line in Fig. 6(a)).

Further, by the movement of the doors 100a, 100b in the closing direction, the lever unit 26 moves against the spring force of the spring 27 against the spring force of the spring pushing portion 55a in the same direction as the moving direction of the spring pushing portion 55a ( See Figure 6(b)).

On the other hand, the switch box 36 moves on the slide rail 40 (omitted in Fig. 6) in the same direction as the moving direction of the spring pushing portion 55b by the spring force of the spring pushing portion 55b against the spring force of the spring pushing portion 55b. .

That is, the doors 100a, 100b are moved in the closing direction, the deformation causes the spring 27 to contract, and the relative positional relationship between the lever unit 26 and the switch case 36 is changed, so that the interval between the detected portion 26b and the detecting portion 28 is narrowed.

As shown in Fig. 6(b), when the doors 100a and 100b of both sides reach the fully closed position, the detected portion 26b of the lever unit 26 abuts against the detecting unit 28. When the detected portion 26b comes into contact with the detecting unit 28, the detection unit 26b outputs a detection signal to the control unit of the door opening and closing device 1. When receiving the detection signal, the control unit determines that the door is completely closed, and causes the locking device that moves the door toward the opening direction to operate. Specifically, for example, by activating the solenoid by the detection signal, the lock lever provided on the solenoid is locked to the doors 100a, 100b, and the movement of the doors 100a, 100b in the opening direction is locked. Further, at this time, the output of the electric motor for turning the pinion of the door opening and closing device 1 may be stopped by the control unit.

As shown in Fig. 6(c), toward the closing direction of the doors 100a, 100b When the closing operation of the door 100b is stopped during the movement, only the door 100a moves in the closing direction, and only the door switch 10 is pushed by the pushing portion 55a fixed to the door 100a. That is, only the pusher unit 26 is directly pushed.

As described above, only the pusher unit 26 is directly pushed, whereby the switch box 36 is moved along the slide rail 40 in the same direction as the moving direction of the spring pushing portion 55a. At this time, the spring 27 hardly contracts, and the interval between the detected portion 26b and the detecting portion 28 is compared with the interval between the states shown in Fig. 6(a), and there is almost no change.

Therefore, the door 100b does not output a detection signal from the door switch 10 when it is not completely closed.

Similarly, as shown in Fig. 6(d), when the doors 100a, 100b are moved in the closing direction and the closing operation of the door 100a is stopped, only the door 100b is moved in the closing direction, and only the door 100b is fixed. The pusher portion 55b pushes the door switch 10. That is, at this time, only the switch case 36 is directly pushed.

As described above, only the switch case 36 is directly pushed, whereby the switch case 36 and the lever unit 26 are moved along the slide rail 40 in the same direction as the moving direction of the spring pushing portion 55b. At this time, the spring 27 hardly contracts, and the interval between the detected portion 26b and the detecting portion 28 is compared with the interval between the states shown in Fig. 6(a), and there is almost no change.

Therefore, when the door 100a is not completely closed, the detection signal is not output from the door switch 10.

<Effect of the embodiment>

(1) As described above, the door opening and closing device 1 according to the present embodiment includes the door switch 10.

The door switch 10 is a door switch for a railway vehicle provided in a railway vehicle having double-open doors 100a and 100b, and is provided to be relatively movable with respect to the substrate 9 (vehicle body), and one door 100a faces the fully closed position. a lever 22 (first receiving portion) that is pushed during movement; a switch box 30 (second receiving portion) that is configured to be movable relative to the substrate 9 and the rod 22 and that is moved toward the fully closed position by the other door 100b; The relative positions of the rod 22 and the switch case 30 form a predetermined relative position, and when the pair of plate portions 24 fixed to the rod 22 abut against the pair of electrodes 25 fixed to the switch case 30, the electronic circuit for detecting the signal is output ( The detecting means); and the spring pusher 22 and the switch box 30 are such that the relative position of the lever 22 and the switch case 30 is not formed as the spring 23 of the predetermined relative position (the relative position when the plate portion 24 abuts against the electrode 25). Push means). Here, the predetermined relative position is such that the lever 22 and the switch case 30 resist the spring force of the spring 23 and are pushed by the slide plates 53a and 53b provided on the two doors 100a and 100b of the double-open type, so that the two The doors 100a, 100b are moved to the relative positions of the lever 22 and the switch box 30 when they are moved to the fully closed position.

According to this configuration, when only one of the two doors 100a and 100b moves to the fully closed position and the other door does not reach the fully closed position, the lever 22 and the switch are caused by the spring force of the spring 23. The relative position of the cartridge 30 is not formed at the predetermined relative position, and the plate portion 24 and the electrode 25 are not in contact with each other. Therefore, the control signal is not output from the door switch 10 to the control portion.

Thereby, it is possible to more reliably detect whether the double-opening doors 100a, 100b are all in the fully closed position without increasing the number of switches.

(2) In the door switch 10, the rod 22 and the switch case 30 are provided to be movable in parallel with respect to the substrate 9 in the opening and closing direction of the door 100a, 100b.

According to this configuration, the door switch 10 can be disposed by a space extending in parallel with the opening and closing direction of the doors 100a and 100b.

Thereby, in the space below the door drive mechanism (electric motor, planetary gear mechanism 4, rack and pinion mechanism, etc.), the door hanging frame fixed to the door edge side of the door 100a when the doors 100a and 100b are fully closed can be used. The door switch 10 is disposed in a laterally long space between the 7a and the door hanger 7b fixed to the door edge side of the door 100b.

(3) The door switch 10 is provided with a limit switch 20.

The limit switch 20 has: a rod 22; a switch box 30 that freely advances and retracts the rod 22; a spring 23 (elastic member) disposed between the rod 22 and the switch box 30; and the rod 22 resists the spring force of the spring 23 with respect to the switch The cartridge 30 is moved by a predetermined amount, and when the pair of plate portions 24 provided on the rod 22 abut against the pair of electrodes 25, an electronic circuit (detection means) for detecting a signal is output.

The limit switch 20 is disposed to be movable in parallel with respect to the substrate 9 in the advancing and retracting direction of the switch box 30 with respect to the lever 22. Further, the lever 22 is pushed against the poppet 53a provided on one of the doors 100a, and the switch box 30 is pushed to the poppet 53b provided on the other door 100b, so that the lever 22 resists against the switchbox 30. When the springs 23 are moved by the elastic force, when the two doors 100a and 100b reach the fully closed position, the lever 22 is moved by the predetermined amount with respect to the switch case 30, and the pair of plate portions 24 are abutted against the pair of electrodes. 25.

According to this configuration, it is possible to surely detect whether or not the double-open type door is in the fully closed position by using the limit switch 20 that outputs the detection signal when the lever 22 moves against the switch case 30 by a predetermined amount against the elastic force of the spring 23. Therefore, for example, it is also possible to ensure the reliability of the door switch 10 by using a highly reliable limit switch which has been widely used in the past.

(4) The door opening and closing device 1 including the door switch 10 described above includes a control unit that receives a detection signal output from the door switch 10. When receiving the detection signal output from the door switch 10, the control unit drives the lock device to lock the doors 100a and 100b to the fully closed position.

According to this configuration, it is possible to surely detect whether or not the double-opening doors 100a and 100b are at the fully closed position, and the detection signal outputted from the limit switch 20 can be used as a signal for determining the timing of locking the doors 100a and 100b.

Thereby, it is possible to prevent the door 100a, 100b from driving the locking device due to an error when it does not reach the fully closed position.

Further, in the present embodiment, the relative movement amount of the lever 22 to the switch case 30 can be increased. In other words, as shown in Fig. 6, when the lever unit 26 is abutted from the urging portion 55a (when the state of the urging portion 55a is indicated by a two-dot chain line in Fig. 6(a)), the door 100a is reached. When the amount of movement of the door 100a from the closed position (the state shown in FIG. 6(b)) and the relative movement amount of the lever unit 26 to the switch case 36 (that is, the amount of deformation of the spring 27), the relative movement amount is The door 100a is doubled in movement.

Therefore, the thin object held by the doors 100a, 100b during the closing operation can be detected without increasing the accuracy of the sensor. That is, the door in the closing action Between 100a and 100b, it is possible to prevent the detection signals of the closing doors 100a and 100b from being output due to an error when the foreign objects cannot be completely closed and the doors 100a and 100b are not completely closed.

(First Modification)

The above embodiment can be implemented by the following modifications.

Fig. 7 is a schematic view for explaining the operation of the first modification of the embodiment. The door opening and closing device according to the first modification differs from the above embodiment in that the door switch configuration is different. Therefore, only the configuration of the door switch will be described, and other configurations will be omitted. In addition, members that are the same as those in the above embodiment are denoted by the same reference numerals.

As shown in Fig. 7, the door switch 11 of the first modification includes a switch case 61, and two poles 62 and 63 on the proximal end side of the switch case 61 are disposed in the switch case 61, and are disposed on the rods 62 and 63. Springs 64 and 65 between the base end and the inner surface of the switch case 61; a magnet 66 fixed to one of the rods 62; and a magnetic sensor 67 fixed to the other rod 63.

Further, in the opening and closing direction of the door, the projecting portions 56a and 56b are disposed at positions facing the rods 62 and 63, respectively. The poppet portions 56a and 56b are coupled to the doors 100a and 100b, respectively, and move in accordance with the movement of the doors 100a and 100b.

The switch box 61 is directly fixed to the substrate 9. That is, the switch box 61 is fixed so as not to be relatively movable to the vehicle body.

The lever 62 is disposed such that its front end protrudes from the switch case 61, and the base end is located inside the switch case 61. The rod 62 is provided to be freely advanced and retractable in the axial direction with respect to the switch box 61. Further, the advancing and retracting direction of the rod 62 is parallel to the opening and closing direction of the door.

A spring 64 is disposed between the rod 62 and the switch case 61. The spring 64 is a push rod 62 from the proximal end side toward the distal end side.

Further, the rod 62 is fixed with a magnet 66 at an intermediate portion in the axial direction. The magnet 66 is fixed to the rod 62 opposite to the side of the rod 63.

Further, as the door 100a is closed, the poppet portion 56a is moved in the closing direction, whereby the front end of the push rod 62 is configured by the spring pushing portion 56a.

The rod 63 is disposed such that its front end projects from the switch case 61 in the opposite direction to the rod 62 with its base end located in the switch case 61. The rod 63 is provided to be freely advanced and retracted toward the axial direction with respect to the switch case 61. Further, the advancing and retracting direction of the rod 63 is parallel to the opening and closing direction of the door.

Further, the rod 63 is disposed at substantially the same position as the rod 62 in the direction orthogonal to the substrate 9 (the depth direction of the paper in FIG. 7). That is, the rods 62 and 63 are disposed so as to be parallel to the vertical direction, so that the central axis of the rod 62 is at the same linear position as the central axis of the rod 63.

A spring 65 is disposed between the rod 63 and the switch case 61. This spring 65 pushes the rod 63 from the proximal end side toward the distal end side.

Further, the rod 63 is fixed to the magnetic sensor 67 at the intermediate portion in the axial direction. The magnetic sensor 67 is fixed to the rod 63 opposite to the side of the rod 62.

Then, as the door 100b is closed, the spring pushing portion 56b is moved in the closing direction, whereby the front end of the push rod 63 is configured by the spring pushing portion 56b.

As shown in Fig. 7(a), in a state where the rods 62, 63 are not pushed by the pushing portions 56a, 56b, the rod 62 is pushed by the spring force of the spring 64. The state in which the slider portion 56a is moved is maintained, and the lever 63 is held by the spring force of the spring 65 toward the slider portion 56b. Therefore, the magnet 66 is held at a position that is not opposed to the magnetic sensor 67.

When the doors 100a, 100b are moved further in the closing direction, the spring pushing portion 56a abuts against the rod 62, and the spring pushing portion 56b abuts against the rod 63, so that the rod 62 resists the spring force of the spring 64 by the elastic thrust of the spring pushing portion 56a. The rod 63 is moved toward the elastic pushing portion 56b side by the elastic thrust of the spring pushing portion 56b against the spring force of the spring pushing portion 56b.

Further, as shown in Fig. 7(b), when the two doors 100a and 100b are normally closed, and the magnets 66 are opposed to the magnetic sensor 67 when they reach the fully closed position. That is, the magnet 66 is brought closest to the magnetic sensor 67.

Here, the magnetic sensor 67 detects the magnetism of the magnet when the magnet 66 is closest in a predetermined range (hereinafter, referred to as the detection range of the magnetic sensor 67), and outputs a detection signal to the control unit of the door opening and closing device. Further, in the present modification, the interval between the levers 62 and 63 is adjusted so that the magnet 66 enters the magnetic sensor only when the magnet 66 is opposed to the magnetic sensor 67 (that is, when the magnet 66 is closest to the magnetic sensor 67). The detection range of 67.

Therefore, when the two doors 100a and 100b reach the fully closed position, the magnetic sensor 67 outputs the detection signal.

Therefore, as shown in Fig. 6(c), the magnetic sensor 67 and the magnet 66 are in a state in which only one of the doors 100a reaches the fully closed position and the other door 100b is stopped in the middle due to the failure of the door opening and closing device 1. They do not oppose each other and do not output a detection signal from the magnetic sensor 67.

Similarly, as shown in Fig. 6(d), due to the door opening and closing device 1, When the door 100a reaches the fully closed position and the door 100a is stopped in the middle, the magnetic sensor 67 and the magnet 66 do not face each other, and the detection signal is not output from the magnetic sensor 67.

(Effect of the first modification)

As described above, the door switch 11 according to the first modification is provided with a lever 62 (first receiving portion) that can be pushed against the substrate 9 (vehicle body) while the one door 100a is moved toward the fully closed position; The rod 63 (second receiving portion) that can be relatively moved when the other substrate 100 and the rod 62 are relatively moved toward the fully closed position; the relative positions of the rod 62 and the rod 63 form a predetermined relative position, the magnet When the proximity detection range is 66, the magnetic sensor 67 (detection means) that outputs the detection signal; and the push rod 62 and the rod 63 are such that the relative positions of the push rod 62 and the rod 63 are not formed into the predetermined relative position ( The magnets 66 enter the springs 64, 65 (the bouncing means) to the relative position within the detection range of the magnetic sensor 67. Here, the predetermined relative position is such that the rod 62 and the rod 63 are pushed against the spring pushing portions 56a and 56b of the double-opening two doors 100a and 100b against the spring force of the springs 64 and 65, so that the two are moved. The relative positions of the rod 62 and the rod 63 when the doors 100a, 100b are moved to the fully closed position.

According to this configuration, only one of the two doors 100a and 100b is moved to the fully closed position, and when the other door does not reach the fully closed position, the spring force of the springs 64 and 65 does not cause The relative position of the rod 62 and the rod 63 forms the above-described predetermined relative position, so that the magnet 66 does not enter the detection range of the magnetic sensor 67, and there is no slave magnetic sensor 67. The control unit outputs a detection signal.

Thereby, it is more sure to detect whether the double-opening doors 100a, 100b are in the fully closed position without increasing the number of switches.

(Second modification)

The above embodiment can be implemented by the following modifications.

Fig. 8 and Fig. 9 are schematic diagrams for explaining the operation of the second modification of the above embodiment. The door opening and closing device according to the second modification differs from the above embodiment in that the door switch configuration is different. Therefore, only the configuration of the door switch will be described, and other configurations will be omitted. In addition, members that are the same as those in the above embodiment are denoted by the same reference numerals.

As shown in Fig. 8, the door switch 12 of the second modification has a shaft 71 that is fixed to the substrate 9 and extends orthogonally to the substrate 9, and is disposed in parallel with the substrate 9, and is provided with a sector that is rotatable around the shaft 71. The first turning member 72 of the plate member; the long-plate-shaped second turning member 73 that is provided to overlap the first turning member 72 and is rotatable around the shaft 71; and the first turning member 72 and the second turning member. a spring 74 between the 73; a magnetic sensor 75 provided in the first rotating member 72; a magnet 76 provided in the second rotating member 73; and a fixed rotation on the substrate 9 to restrict the rotation of the first rotating member 72 (arrow in Fig. 8) The first stopper 77 of the rotation in the R1 direction; and the second stopper 78 fixed to the substrate 9 to restrict the rotation of the second rotation member 73 (the rotation in the direction of the arrow R2 in Fig. 8).

Further, in the doors 100a and 100b, the lever-shaped projecting portions 57a extending in parallel with the opening and closing direction of the door are fixed by the support members 51a and 51b, respectively. 57b.

The first turning member 72 is rotatably coupled to the periphery of the shaft 71 in the vicinity of the center of the arc. Further, in the vicinity of the arcuate edge portion of the first turning member 72, the magnetic sensor 75 is fixed in the vicinity of the linear edge portion on the opposite side to the linear edge portion that is in contact with the first stopper 77. .

The length of the second turning member 73 is a long plate-shaped member that is substantially equal to the radius of the first turning member 72, and the vicinity of one end is rotatably coupled around the shaft 71, and the magnet 76 is fixed to the vicinity of the other end. Further, the second turning member 73 has a distance from the shaft 71 to the magnet 76 and a distance from the shaft 71 to the magnetic sensor 75.

The spring 74 is in the vicinity of a linear edge portion that abuts against the first stopper 77 of the first rotating member 72, and is fixed to a substantially central portion in the radial direction of the first rotating member 72. Further, the spring 74 fixes the other end to a substantially central portion in the longitudinal direction of the second rotating member 73. Further, the spring 74 pushes the first turning member 72 to rotate in one direction around the shaft 71 (in the direction around the counterclockwise direction in Fig. 8 and indicated by an arrow R1), and pushes the second turning member 73 toward the second turning member 73. The direction opposite to the one direction (the direction around clockwise in Fig. 8 is indicated by an arrow R2) is rotated around the shaft 71.

Therefore, when the first turning member 72 and the second turning member 73 do not have an external force (a force other than the spring 74), as shown in Fig. 8(a), the first turning member 72 abuts against the first stop. The state of the member 77 is maintained, and the second turning member 73 is held in contact with the second stopper 78.

In this state, in the direction around the shaft 71, the magnetic sensor 75 and the magnetic The irons 76 are separated from each other.

Then, as the doors 100a and 100b are closed, the spring pushing portions 57a and 57b are moved in the closing direction. As shown in Fig. 8(b), the spring pushing portions 57a and 57b are respectively abutted against the first rotating member. 72 and the edge of the second turning member 73. Specifically, the spring pushing portion 57 a is in contact with an edge portion that extends in a straight line toward the radial direction of the first turning member 72 . Further, the spring pushing portion 57b is in contact with an edge portion that extends in a straight line toward the longitudinal direction of the second turning member 73.

Further, the spring pushing portions 57a and 57b are moved in the closing direction, whereby the first turning member 72 is pushed toward the spring pushing portion 57a, and is moved away from the first stopper 77 against the spring force of the spring 74. The direction (the direction of the arrow R2 in Fig. 8) is rotated around the shaft 71.

Further, the second turning member 73 is pushed by the spring pushing portion 57b, and is rotated around the shaft 71 in a direction away from the second stopper 78 (direction of the arrow R1 in Fig. 8) against the spring force of the spring 74.

That is, the urging portions 57a, 57b are moved in the closing direction, whereby the magnetic sensor 75 and the magnet 76 are moved toward each other.

Further, when the two doors 100a and 100b are normally closed, and when both of the doors reach the fully closed position, as shown in Fig. 8(c), the magnetic sensor 75 is superposed on the magnet 76. That is, the magnet 76 is brought closest to the magnetic sensor 75.

Here, the magnetic sensor 75 detects the magnetic gas of the magnet when the magnet 76 approaches in a predetermined range (hereinafter, referred to as the detection range of the magnetic sensor 75), and outputs a detection signal to the control unit of the door opening and closing device. Moreover, in the present modification, When only the magnet 76 is superposed on the magnetic sensor 75 (that is, when the magnet 76 is closest to the magnetic sensor 75), the interval between the first rotating member 72 and the second rotating member 73 (the interval in the direction parallel to the pre-axis 71) is adjusted. The magnet 76 is made to enter the detection range of the magnetic sensor 75.

Therefore, the magnetic sensor 75 outputs a detection signal only when both of the doors 100a and 100b reach the fully closed position.

Therefore, as shown in Fig. 9(a), due to the failure of the door opening and closing device 1, only one of the doors 100a reaches the fully closed position, and the other door 100b is stopped in the middle, the magnetic sensor 75 and the magnet The 76 does not overlap and does not output a detection signal from the magnetic sensor 75.

Similarly, as shown in Fig. 9(b), due to the failure of the door opening and closing device 1, only one of the doors 100b reaches the fully closed position, and the other door 100a is stopped in the middle, the magnetic sensor 75 and the magnet The 76 does not overlap and does not output a detection signal from the magnetic sensor 75.

(Effect of the second modification) (1)

As described above, the door switch 12 according to the second modification is provided with a first turning member 72 that is biased when the door 100a is moved toward the fully closed position, and the first door member 12 is provided to be relatively rotatable with respect to the substrate 9 (vehicle body). a second turning member 73 (second receiving portion) that is rotatable when the other door 100b is moved toward the fully closed position, and the first turning member 72 is provided to be rotatable relative to the base member 9 and the first turning member 72. The relative position of the second turning member 73 forms a predetermined relative position, and the magnet 76 is close to the detection. In the range, the magnetic sensor 75 (detection means) that outputs the detection signal; and the first rotating member 72 and the second rotating member 73 are pushed, so that the relative positions of the first rotating member 72 and the second rotating member 73 are not formed. A spring 74 (boosting means) which is a predetermined relative position (the position where the magnet 76 enters the detection range of the magnetic sensor 75). Here, the predetermined relative position is such that the first turning member 72 and the second turning member 73 are pushed against the spring pushing portions 57a and 57b provided in the double-opening two doors 100a and 100b against the spring force of the spring 74. The relative positions of the first turning member 72 and the second turning member 73 when the two doors 100a and 100b are moved to the fully closed position.

According to this configuration, when only one of the two doors 100a and 100b moves to the fully closed position and the other door does not reach the fully closed position, the first swing is caused by the spring force of the spring 74. The relative position of the member 72 and the second turning member 73 is not formed at the predetermined relative position, and the magnet 76 does not enter the detection range of the magnetic sensor 75. Therefore, the control unit does not output a detection signal from the magnetic sensor 75. .

Therefore, it is possible to more reliably detect whether the double-open doors 100a, 100b are all in the fully closed position without increasing the number of switches.

(2)

In the door switch 12, the first turning member 72 and the second turning member 73 are rotatably provided around the shaft 71 (rotating shaft) fixed to the substrate 9, and the shaft 71 is opposed to the flat doors 100a and 100b. The vertical direction (the width direction of the vehicle) extends.

Further, the first turning member 72 and the second turning member 73 are formed into a flat plate. The shape is configured such that a direction parallel to the shaft 71 forms a thickness direction. Thereby, in the width direction of the vehicle, the space occupied by the door switch 12 can be made small.

(3)

In the door switch 12, when the magnetic sensor 75 (first detecting unit) provided in the first rotating member 72 and the magnet 76 (second detecting unit) provided in the second rotating member 73 form a predetermined positional relationship, When the magnet 76 enters the detection range of the magnetic sensor 75, the magnetic sensor 75 outputs a detection signal. The magnetic sensor 75 is disposed in the first turning member 72 at a position farther from the shaft 71 than the position of the spring pushing portion 57a. Further, the magnet 76 is disposed in the second turning member 73, and is located farther from the shaft 71 than the position where the spring pushing portion 57a is pushed.

According to this configuration, the amount of movement of the doors 100a and 100b in the closing direction (the amount of movement after the first turning member 72 and the second turning member 73 are abutted) is compared between the magnetic sensor 75 and the magnet 76. The amount of change in relative position becomes larger. Thereby, the thin object of the doors 100a, 100b sandwiched in the closing operation can be detected without increasing the accuracy of the sensor. In other words, it is possible to easily detect the detection signals that the doors 100a and 100b are closed due to the erroneous output when the doors 100a and 100b are not completely closed due to the foreign matter being caught between the doors 100a and 100b during the closing operation.

(Third Modification)

In the second modification, the spring 74 is not limited to the case where the spring 74 is provided between the first turning member 72 and the second turning member 73. The figure shows.

In this configuration, the first spring holding portion 81 that protrudes from the substrate 9 is fixed in the vicinity of the first stopper 77 of the substrate 9. A second spring holding portion 82 that protrudes from the substrate 9 is fixed in the vicinity of the second stopper 78. Further, a first spring 83 is provided between the first spring holding portion 81 and the first rotating member 72. The first spring 83 extends the first turning member 72 to bring the first turning member 72 closer to the first stopper 77. A second spring 84 is provided between the second spring holding portion 82 and the second rotating member 73. The second spring 84 extends the second turning member 73 to bring the second turning member 73 closer to the second stopper 78.

Therefore, when the external force (force other than the spring 74) does not act on the first turning member 72 and the second turning member 73, as shown in the tenth (a) diagram, the first turning member 72 is brought into contact with the first stop. The state of the member 77 is maintained, and the second turning member 73 is held in contact with the second stopper 78.

Further, when both the doors have reached the fully closed position, as shown in Fig. 10(b), the magnetic sensor 75 overlaps with the magnet 76.

As described above, according to the configuration shown in Fig. 10, the detection signal can be output from the door switch 12 only when both of the doors reach the fully closed position.

(Fourth Modification)

In the third modification, the first turning member 72 is not limited to the case of forming a sector. For example, in the eleventh diagram, as shown in the first rotating member 72', an L-shape or a V-shape may be formed. At this time, the first rotating member can be made The weight of 72' is reduced, and the space required for the rotation of the first turning member 72' can be reduced.

Further, in the second to fourth modifications, the rotation axis of the first turning member 72 and the turning axis of the second turning member 73 are not limited to the same rotating shaft (shaft 71), and the first turning member 72 may be used. The rotary shaft is separated from the rotary shaft of the second rotary member 73, and is disposed at different positions.

The embodiment and the modifications of the present invention have been described above, but the present invention is not limited to the above-described embodiments and modifications, and various modifications can be made and implemented within the scope of the claims.
