Description

  The present invention relates to a door pinching detection system applied to a door mechanism of a railway vehicle, and in particular, incorporates a contact sensor in a door rubber and determines whether door pinching has occurred using a photoelectric sensor. The present invention relates to a door pinching detection system.

  In railway vehicles, crew members often open and close the left and right vehicle doors, but when the vehicle door is closed, a part of an object or person is caught between a pair of door rubbers. There is a risk of door pinching. This pinching can be dealt with by a crew member's confirmation work. However, in recent years, many home doors are being adopted in railway vehicles, and when it is sandwiched between the home door and the vehicle, it becomes a blind spot of the crew, and it is difficult for the crew to find the door clamp. As described above, since there is a limit to the attention of the crew, it is desired that the door pinching can be automatically detected.

  For example, as a door pinching detection system for detecting door pinching, there is one described in Patent Document 1 below. In this door pinching detection system, as shown in FIG. 14, a non-contact power feeding device 200 is provided between the vehicle door side X and the vehicle main body side Y, and between the vehicle door side X and the vehicle main body side Y. Power supply and information transmission are possible. A cord switch 220 is incorporated in a door rubber 204 attached to an end of the vehicle door 202 in the opening / closing direction, and the cord switch 220 detects a door pinching. Thus, according to this door pinching detection system, the contactless power feeding device 200 is arranged in a narrow space of the upper frame portion 205 located above the vehicle door 202, and an accident caused by door pinching is achieved while improving the efficiency of the space. Is preventing.

  However, the door pinching detection system described in Patent Document 1 has the following problems. That is, as shown in FIG. 14, the cord switch 220 is not built in the upper end portion and the lower end portion of the door end rubber 204, and a hard edge rubber 223 is attached. Thus, it is necessary to provide hard portions that are not elastically deformed at the upper end portion and the lower end portion of the door-end rubber 204 so that the cord switch 220 cannot detect the door pinching. For this reason, for example, when an object at a very low position is sandwiched between the hard edge rubbers 223, the door pinching cannot be detected, and there is room for improving the detection of the door pinching in the conventional door pinching detection system.

  Then, this invention aims at providing the door pinching detection system which can improve safety | security with respect to the door pinching in a railway vehicle in order to solve the above-mentioned subject.

A door pinching detection system according to the present invention has a pair of door rubbers attached to the ends of a pair of vehicle doors in a railway vehicle, and a contact sensor built in the door rubber. A door-side coupler and a vehicle body-side coupler for supplying power to the contact sensor and receiving an electric signal from the contact sensor in a non-contact manner, and an electric signal is received from the contact sensor connected to the vehicle body-side coupler. A controller that determines that door pinching has occurred, and is arranged on a contact line where the door rubber contacts each other, and is located on the upper frame portion positioned above the vehicle door When a photoelectric sensor is attached and the controller is connected to the photoelectric sensor and receives an output detection signal that is output when the photoelectric sensor is blocked by signal light, or the contact sensor outputs Electricity When receiving the items, which is configured to determine that Tohasami has occurred, the at the end of the opening and closing direction of the vehicle door, the first mounting member and the second mounting cross-section substantially L-shaped A groove portion in which the member is provided as a separate body, and the inward end portion of the first attachment member and the inward end portion of the second attachment member are opposed to each other, and the neck portion where the door rubber is recessed is assembled. The door rubber is attached to the second attachment member using a connecting member in a state where the neck is fitted into the groove .

  In this case, when the vehicle door closes, for example, if a thin object at an extremely low position is sandwiched between door rubbers, the contact sensor does not transmit an electric signal (door pinching detection signal), but the photoelectric sensor An output detection signal is transmitted to the controller. Thereby, the controller can determine that the door is pinched and can take measures such as opening the vehicle door. Thus, since it is possible to detect the door pinching by the double check of the contact sensor and the photoelectric sensor, it is possible to improve safety against the door pinching in the railway vehicle.

  Further, in the door pinching detection system according to the present invention, a plurality of door mechanisms in the railway vehicle are each provided with a display means capable of being lit on the upper frame portion, and the controller is provided on the plurality of door mechanisms. Of the attached display means, the display means attached to the door mechanism that has been determined to have door pinching may be lit.

  In this case, among the display means attached to the plurality of door mechanisms, the display means of the door mechanism in which the door is actually pinched is turned on. For this reason, crew members and station staff can confirm the door mechanism in which door pinching occurs earlier, and can take measures to release door pinching earlier. In particular, in the situation where many home doors are being adopted in recent years, when the door is sandwiched between the home door and the vehicle, it is difficult to find the door pin. it can.

  Further, in the door pinching detection system according to the present invention, a first mounting member and a second mounting member having a substantially L-shaped cross section are provided separately from each other at an end portion in the opening and closing direction of the vehicle door, The inward end portion of the first attachment member and the inward end portion of the second attachment member constitute a groove portion that faces the neck portion in which the door rubber is depressed, and the door rubber is It is good to be attached to the 2nd attachment member using a connecting member in the state where the neck part fits into the slot.

  In this case, even if a relatively large hollow hole for incorporating the contact sensor is formed in the door rubber, the door rubber is firmly and stably fixed. Therefore, local stress is not generated in the door-end rubber, and it is possible to prevent an object sandwiched between the door-end rubbers from becoming difficult to pull out compared to the conventional case.

  ADVANTAGE OF THE INVENTION According to this invention, the door pinching detection system which can improve safety | security with respect to the door pinching in a railway vehicle is provided.

It is the schematic which showed the door mechanism to which the conventional door pinching detection system was applied.

  The door pinching detection system according to the present invention will be described below with reference to the drawings. FIG. 1 is a view showing a door mechanism 1 of a railway vehicle to which the door pinching detection system of this embodiment is applied. In the door mechanism 1, the left and right vehicle doors 2 </ b> L and 2 </ b> R can move in the left and right opening / closing directions with respect to the vehicle body 3 as shown in FIG. Specifically, when a crew member operates a door opening button (not shown) or a door closing button (not shown), the left and right vehicle doors 2L and 2R are driven by motors (not shown) mounted on the vehicle body 3. It opens and closes via a mechanism.

  A door rubber 4L extending in the vertical direction is attached to the right end of the left vehicle door 2L, and a door rubber 4R extending in the vertical direction is attached to the left end of the right vehicle door 2R. These door-end rubbers 4L and 4R are for alleviating the impact when door pinching occurs. Here, the pinch means that a part of an object or a person is sandwiched between the left and right door rubbers 4L, 4R when the left and right vehicle doors 2L, 2R are closed. The door mechanism 1 includes a door pinching detection system 10 for automatically detecting door pinching.

  As shown in FIG. 1, the door pinching detection system 10 includes a tape switch 20 mounted in the left door rubber 4L, a door-side coupler 30 that performs non-contact (wireless) information transmission and power feeding, and A vehicle body side coupler 40 and a controller 50 that determines whether or not door pinching has occurred are provided. Here, FIG. 2 is a front view of the left vehicle door 2L, and FIG. 3 is a front view of the left door rubber 4L.

  The tape switch (contact sensor) 20 is for detecting a door pinching and extends in the vertical direction as shown in FIG. The vertical length of the tape switch 20 is about 1500 mm, which is shorter than the vertical length of the door rubber 4L. The tape switch 20 is connected to the door-side coupler 30 via a lead wire 21 so that an electrical signal can be transmitted to the door-side coupler 30. Here, FIG. 4 is a cross-sectional view taken along the line AA of FIG.

  Further, as shown in FIG. 4, the tape switch 20 is disposed in the hollow hole 4a of the door-end rubber 4L, and when the door pinching occurs, the tip 4b on the right side of the door-end rubber 4L in FIG. 4, the tip 4 b presses the convex portion 22 located at the center of the tape switch 20. Thereby, a pair of electrode plates (not shown) of the tape switch 20 come into contact with each other, and the electric circuit is turned on. As a result, a door pinching detection signal (electrical signal) is transmitted from the tape switch 20 to the door side coupler 30. On the other hand, when the front end 4b is not pushed, the pair of electrode plates of the tape switch 20 are separated from each other, and the door pinching detection signal is not transmitted from the tape switch 20 to the door side coupler 30.

  In the tape switch 20 of this embodiment, the door pinching of the inclusion of 3 mm-25 mm is detected by the device of the shape of the door end rubber 4L. That is, when an object of about 3 mm to 25 mm is sandwiched between the left and right door rubbers 4L and 4R, the tip side of the left door rubber 4L is elastically deformed, so that the pair of electrode plates of the tape switch 20 come into contact with each other. It is supposed to be. The door mechanism 1 is provided with a separate door closing sensor for detecting the closing of the left and right vehicle doors 2L, 2R, and an object larger than 25 mm is sandwiched between the left and right door rubbers 4L, 4R. The door closing sensor does not detect the closing of the vehicle doors 2L, 2R.

  The door side coupler 30 and the vehicle body side coupler 40 are for receiving a door pinching detection signal (electric signal) from the tape switch 20 and supplying power to the tape switch 20. The door side coupler 30 is integrally attached to the upper part of the left vehicle door 2L. On the other hand, the vehicle body side coupler 40 is fixed to the upper frame portion 5 (see FIG. 1) of the vehicle main body 3 positioned above the vehicle door 2L. Since FIG. 1 is a schematic diagram, FIG. 1 does not show that the vehicle body side coupler 40 is mounted on the upper frame portion 5. Here, FIG. 5 is a plan view of the upper frame portion 5.

  As shown in FIG. 5, the door-side coupler 30 and the vehicle body-side coupler 40 face each other in a non-contact manner (opposite to the front) when the left and right vehicle doors 2L and 2R are closed. The door side coupler 30 and the vehicle body side coupler 40 have a coil (not shown) and a magnetic core (not shown), and can supply power by mutual induction action of electromagnetic induction. The door-side coupler 30 and the vehicle body-side coupler 40 of the present embodiment are obtained by remodeling a commercially available casing, and the sizes of the coils are the same. Even if the door-side coupler 30 and the vehicle body-side coupler 40 are slightly opposite from each other because an object is sandwiched between the left and right door-end rubbers 4L and 4R, normal communication can be performed. It has become. A scale is displayed on the door side coupler 30 and the vehicle body side coupler 40 in order to clarify the mounting position. 6 is a front view taken along the line BB in FIG. 5, and FIG. 7 is a front view taken along the line CC in FIG.

  As shown in FIG. 6, the door-side coupler 30 is connected to the lead wire 21 (see FIG. 3) of the tape switch 20 via a connection cable 31. Therefore, the wiring on the door side is completed only on the door side, power is supplied from the door-side coupler 30 to the tape switch 20, and the door pin detection from the tape switch 20 to the door-side coupler 30 is detected. A signal (electrical signal) is transmitted. On the other hand, the vehicle body side coupler 40 is connected to the controller 50 via the connection cable 41 as shown in FIG. For this reason, the wiring on the vehicle body side is completed only on the vehicle body side, power is supplied from the power source (not shown) of the controller 50 to the vehicle body side coupler 40, and control is performed from the vehicle body side coupler 40. A door clamp detection signal is transmitted to the container 50. In this way, the power feeding cable connecting the door side and the vehicle body side is abolished, so that the conventional problems of disconnection and wear of the power feeding cable and the arrangement in the narrow space of the upper frame portion 5 are eliminated. Yes.

  When the controller 50 receives a door pin detection signal from the tape switch 20 via the door side coupler 30 and the vehicle body side coupler 40 when the left and right vehicle doors 2L and 2R are closed, door pinching occurs. It is comprised so that it may be judged. When the door pinching occurs, the crew member can release the door pinching state by operating the door opening button.

  By the way, in the tape switch 20 built in the door end rubber 4L as described above, the door pinching may not be accurately detected when the door pinching occurs in the lower part of the vehicle doors 2L, 2R. That is, when a thin object at an extremely low position is sandwiched between the left and right door rubbers 4L and 4R, it may not be determined that the door is pinched. Hereinafter, this problem will be described.

  As shown in FIG. 3, a tape switch 20 is built in the center of the door rubber 4L, but a hard rubber 23 is built in the upper and lower ends of the door rubber 4L. Has been. Since the rubber plugs 4L and 4R are soft, the rubber pad 23 is used to block the door rubbers 4L and 4R from being crushed too much when the left and right vehicle doors 2L and 2R are closed. . In recent railway vehicles, a hard part at the bottom end of the door rubber is used for safety so that the vehicle doors 2L and 2R are not closed when the wheel of a stroller is sandwiched between the door rubbers 4L and 4R. (Padded rubber) is provided.

  For this reason, when the contact sensor is incorporated in the door rubber 4L, it is necessary to provide a hard portion such as the rubber pad 23, and the contact sensor is incorporated in the entire vertical direction of the door rubber 4L. I can't let you. Thus, there has conventionally been a range in which door pinching cannot be detected at the upper end portion and the lower end portion of the door rubber 4L incorporating the contact sensor. In the present embodiment, as shown in FIG. 3, the vertical length of the door rubber 4L is about 1800 mm, whereas the door pinching detection range L1 by the tape switch 20 is an intermediate portion of the door rubber 4L. 1460 mm. The door pinching undetectable range L2 by the tape switch 20 is 100 mm at the upper end of the door rubber 4L, and the door pinching undetectable range L3 by the tape switch 20 is 200 mm at the lower end of the door rubber 4L.

  Therefore, in the present embodiment, as shown in FIG. 1, a beam sensor (photoelectric sensor) 60 is provided in the door pinching detection system 10 to deal with the above-described problems, and the tape switch 20, the beam sensor 60, and the like. The door is detected by double check. Further, an indicator lamp (display means) 70 is provided for notifying that the door pinching detection system 10 has door pinching. Here, FIG. 8 is a side view taken along line DD in FIG. 5, and FIG. 9 is a side view taken along line EE in FIG. FIG. 10 is a front view of FIGS. 8 and 9 when viewed from the right side.

  As shown in FIGS. 8 and 10, the beam sensor 60 is attached to a member constituting the upper frame portion 5 of the vehicle main body 3, and is disposed on a contact line O <b> 1 where the left and right door rubbers 4 </ b> L contact each other. (See FIG. 1 and FIG. 6). This beam sensor 60 is integrally provided with a projector that projects infrared light and a light receiver that receives infrared light, and the infrared light (signal light) is reflected by an object sandwiched between the left and right door rubber 4L. Is a reflection type photoelectric sensor which detects an output by a light receiving unit and obtains an output detection signal.

  As shown in FIG. 10, the beam sensor 60 is connected to the controller 50 via the connection cable 61, and transmits the detected output detection signal to the controller 50. Here, the controller 50 determines that the door is pinched when the output detection signal is received during the set time (about several seconds) after the crew member operates the door closing button. ing. For this reason, for example, even if an object or a person passes between the vehicle doors 2L and 2R and blocks infrared rays while the vehicle doors 2L and 2R are open, it is not determined that the door is pinched. Further, as shown in FIG. 8, the beam sensor 60 is arranged so as to be hidden from the outside by the outer plate 6 which is the surface of the upper frame portion 5, and infrared rays pass through the horizontal portion 7 of the outer plate 6. A passage hole 7a is formed. In addition, the electronic device arrange | positioned at the upper frame part 5 is made invisible by the passenger in the vehicle by the duck member 8.

  As shown in FIGS. 9 and 10, the indicator lamp 70 is attached to a member constituting the upper frame portion 5 of the vehicle body 3, and is arranged on the left side of FIG. 10 from the beam sensor 60. The indicator lamp 70 is connected to the controller 50 via the connection cable 71, and is lit by a lighting signal transmitted when the controller 50 determines that the door is pinched. Further, as shown in FIG. 9, the indicator lamp 70 is attached to an attachment hole 7 b formed in the horizontal portion 7 of the outer plate 6, and the lighting portion of the indicator lamp 70 is exposed to the outside from the horizontal portion 7. Yes. Thus, when a door pinching occurs, a crew member and a station attendant on the platform can confirm the lighting of the indicator lamp 70 and can know the occurrence of the door pinching. Here, FIG. 11 is a diagram showing a side structure GK of a railway vehicle to which the door pinching detection system 10 of the present embodiment is applied.

  As shown in FIG. 11, three door mechanisms 1 are configured in the side structure GK, and a door pinching detection system 10 is applied to each door mechanism 1. As described above, the indicator lamps 70 that can be turned on from outside the vehicle are attached to each upper frame portion 5. For this reason, the indicator lamp 70 lights only in the door mechanism 1 in which the door pinching has occurred among the three door mechanisms 1. As a result, the crew and the station staff can check which door mechanism 1 is causing door pinching earlier, and take measures to release door pinching such as opening the left and right vehicle doors 2L and 2R earlier. Can take. The indicator lamp 70 is turned off by a control command from the controller 50 when the left and right vehicle doors 2L and 2R are opened and the state between the doors is released. The number of door mechanisms 1 and indicator lamps 70 provided is not limited to three, and the same number of indicator lights 70 are provided according to the number of door mechanisms 1.

  The effect of the door pinching detection system 1 configured as described above will be described. When the left and right vehicle doors 2L and 2R are closed, a part of an object or a person is caught between the door rubbers 4L and 4R in the door pinching detection range L1 (see FIG. 3) in the middle of the door rubber 4L. Then, a door pinching detection signal (electrical signal) is transmitted from the tape switch 20 to the controller 50. As a result, the controller 50 can determine that the door is pinched and can deal with the crew member opening the left and right vehicle doors 2L, 2R.

  On the other hand, when the left and right vehicle doors 2L and 2R are closed, for example, if a thin object at an extremely low position is sandwiched between the door rubbers 4L and 4R, the tape switch 20 does not transmit a door pinching detection signal. However, even in this case, the beam sensor 60 detects the infrared ray reflected by the thin object by the light receiving unit, and transmits an output detection signal to the controller 50. As a result, the controller 50 can accurately determine that the door is pinched, and can deal with the crew member opening the left and right vehicle doors 2L, 2R. Thus, according to the present embodiment, since it is possible to detect the door pinching by the double check of the tape switch 20 and the beam sensor 60, it is possible to improve safety against the door pinching in the railway vehicle.

  Moreover, according to this embodiment, the indicator lamp 70 is each provided according to each door mechanism 1, and the indicator lamp 70 lights in the door mechanism 1 in which the door pinching has arisen. The lighting of the indicator light 70 can be confirmed by crew members and station staff on the platform. For this reason, a crew member and a station attendant can confirm the door mechanism 1 in which door pinching occurs earlier, and can take measures to release door pinching earlier. In particular, in the situation where many home doors are being adopted in recent years, it is difficult to find the door pinch when it is pinched between the home door and the vehicle. Can do.

  By the way, in this embodiment, there exists the characteristic in the attachment state (refer FIG. 4) of the door-end rubber 4L with respect to the front-end | tip part of the vehicle door 2L. Hereinafter, before explaining the attachment state of the door-end rubber 4L of the present embodiment, the attachment state of the conventional door-end rubber 104L will be described with reference to FIG. Note that the conventional constituent members will be described with reference numerals in the 100s.

  As shown in FIG. 12, the conventional door-end rubber 104L includes a head portion 104c having a substantially dome-shaped cross section, a trunk portion 104d having a rectangular cross section, and a neck portion recessed between the head portion 104c and the trunk portion 104d. 104e. On the other hand, the front end portion (right side in FIG. 12) of the conventional vehicle door 102L is provided with a first mounting member 102a having an L-shaped cross section on the upper side in FIG. 12, and a U-shaped cross section on the lower side in FIG. A second mounting member 102b in which the portion and the portion having an L-shaped cross section are coupled is provided.

  The first mounting member 102a and the second mounting member 102b are integrally fixed in advance, and the inward end of the first mounting member 102a and the inward end of the second mounting member 102b are opposed to each other. The groove portion MZ for assembling the neck portion 104e of the door end rubber 104L was configured. Thus, in the conventional attachment of the door-end rubber 104L, the door-end rubber 104L is inserted from above (from the upper side in the direction perpendicular to the paper surface of FIG. 12) so that the neck 104e of the door-end rubber 104L fits into the groove MZ. It was installed. For this reason, at the time of replacement in a vehicle, the door rubber 104L had to be bent and attached.

  On the other hand, in the door-end rubber 4L of the present embodiment, the door-end rubber 4L cannot be inserted and attached from above so as to fit into the groove MZ as in the conventional case. This is because the door rubber 4L cannot be bent and attached as shown in FIG.

  Therefore, the door rubber 4L of the present embodiment is attached by modifying the tip of the conventional vehicle door 102L as shown in FIG. FIG. 13 is a view for explaining a method of attaching the door end rubber 4L of the present embodiment. In FIG. 13, members (parts) corresponding to the conventional constituent members shown in FIG. 12 are shown without the reference numerals in the 100s. First, in the present embodiment, a first mounting member 2a having an L-shaped cross section is provided on the upper side of FIG. 13 at the front end of the vehicle door 2L, and is separated from the first mounting member 2a on the lower side of FIG. As shown, a second mounting member 2b having an L-shaped cross section is provided.

  First, the door rubber 4L is moved in the direction indicated by the arrow in FIG. 13, and the neck 4e is fitted to the inward end of the first mounting member 2a. Next, the second mounting member 2 b is moved in the direction indicated by the arrow in FIG. 13, and the inward end of the second mounting member 2 b is fitted to the neck 4 e while using the screw seat 9. Finally, the second mounting member 2b is fixed with the bolt BT and the screw seat 9. Thus, the door rubber 4L is attached to the front end of the vehicle door 2L with the neck 4e fitted into the groove MZ.

  In this embodiment, since the door rubber 4L is attached in this way (see FIG. 4), the tape switch 20 is built in the door rubber 4L, but the door rubber 4L is firmly and stably fixed. Has been. In other words, it is not forcibly attached to the tip of the vehicle door 2L in a state where the door rubber 4L is curved.

As described above, the door pinching detection system 10 according to the present invention has been described. However, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the present invention.
For example, in this embodiment, the tape switch 20 is incorporated in the left door-end rubber 4L to detect the pinching of the door. However, the tape switch 20 may be incorporated in the right door rubber 4R, or the tape switch 20 may be incorporated in both the left door rubber 4L and the right door rubber 4R to detect the door pinching. .
In this embodiment, the tape switch 20 is used as a contact sensor (pressure sensor). However, the contact sensor is not limited to the tape switch 20 and can be appropriately changed. For example, a cable switch or a cord switch may be used.
In the present embodiment, a reflective photoelectric sensor (beam sensor 60) integrally provided with a projector and a light receiver is used as the photoelectric sensor. However, the photoelectric sensor is not limited to the reflection type photoelectric sensor, and can be changed as appropriate. For example, a transmission type photoelectric sensor in which a projector and a light receiver are provided separately, or a mirror reflection type photoelectric sensor provided with a reflection mirror. There may be.
