Description

  The present invention relates to a cable type switch that detects contact of an object to be detected, and more particularly to a cable type switch suitable for use in an opening / closing device mounted on a vehicle such as an automobile.

  An open / close device that opens and closes doors, tailgates, window glass, sunroofs and other open / close bodies provided in vehicles such as automobiles by a drive source sandwiches an obstacle (detected object) by the open / close body that opens and closes. In order to prevent this, a pinching prevention function is provided. As a sensor for detecting pinching, an elastically deformable cable-shaped pressure-sensitive sensor (cable switch) is used. It is attached to the vehicle body side opening part which opposes a part up and down.

As a technique using a cable type switch provided in such a vehicle, for example, one described in Patent Document 1 is known. In the cable type switch described in Patent Document 1, a pair of electrode members (conductive members) that do not come into contact with each other under a no-load state on the tube are spirally provided inside the flexible tube. ing. A diagnostic resistor (inspection resistor) for diagnosing a short circuit or disconnection of each conductive member when no load is applied to the tube is electrically connected to one end side of each conductive member, and the other end side of each conductive member Is electrically connected to a control device for performing control such as stopping the switchgear when the cable switch is in an operating state (on state). And this cable type switch is hold | maintained at the hollow switch accommodating part of the weather strip (elastic holder) attached to a window frame.

  However, according to the cable-type switch described in the above-mentioned Patent Document 1, an inspection resistor is provided on one end side of each conductive member, and a control device is provided on the other end side. The following problems may occur when the cable type switch is attached to the housing portion. In other words, when the cable type switch is pushed into the switch holder of the elastic holder from the one end side and attached, a predetermined amount of load is applied to the cable type switch due to the frictional resistance acting between them. Therefore, there is a possibility that one end side of the cable type switch may be twisted or bent, and as a result, there may be a problem that the inspection resistor provided on one end side of each conductive member is disconnected.

  Therefore, for example, it is conceivable to connect the inspection resistor after the cable type switch is mounted in the switch accommodating portion of the elastic holder. However, in this case, the work process on the user side (car manufacturer side) who attaches the cable type switch to the elastic holder becomes complicated. Therefore, it is desirable to deliver the cable type switch to the user side in a state where components such as inspection resistors are assembled.

  An object of the present invention is to provide a cable type switch that can improve the handleability even in a state where components are assembled.

  The cable-type switch of the present invention is a cable-type switch that includes conductive members that are elastically deformed by contact with an object to be detected and are capable of contacting each other, the first conductive member having flexibility, and the first conductive member.

Between the other end side of the fourth conductor and the other end side of the fourth conducting wire, a test resistor is electrically connected to one of them, and a contact detection means for detecting the contact of each of the conductive members is electrically connected to the other. It is characterized by being connected.

  The cable-type switch of the present invention is a cable-type switch that includes conductive members that are elastically deformed by contact with an object to be detected and that can contact each other, and includes a flexible cylindrical first conductive member, A first conductive wire provided along a longitudinal direction of the first conductive member and electrically contacting the first conductive member; and provided in the first conductive member side by side with the first conductive wire; A second conductive wire provided in a state of being electrically insulated from the conductive wire, a second cylindrical conductive member having flexibility and provided on the outer periphery of the first conductive member via a predetermined gap; A third conductive wire provided in the second conductive member along the longitudinal direction thereof and electrically contacting the second conductive member; and provided in the second conductive member alongside the third conductive wire; A fourth conductor provided in an electrically insulated state from the three conductors; An elastic insulator provided between the conductive members and forming the predetermined gap under no load on the second conductive member; and one end side of the first conductive wire and the second conductive wire And electrically connecting one end side of the third conducting wire and one end side of the fourth conducting wire, and electrically connecting the other end side of the first conducting wire and the other end of the third conducting wire.

Since the contact detection means for connecting and detecting the contact of each conductive member is electrically connected to one of the other, the inspection resistance and the contact detection means can be concentrated on the other end side of each conductive member. Accordingly, since it is not necessary to provide a component on one end side of each conductive member, it is not necessary to worry about twisting or bending on one end side of each conductive member, and the handling property can be improved in the state where the inspection resistor is assembled.

  Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. 1 is a side view showing a one-box type vehicle, FIG. 2 is an explanatory diagram for explaining the structure of a switchgear provided with a cable type switch, and FIG. 3 is an explanatory diagram for explaining a control system of the switchgear of FIG. Respectively.

  As shown in FIG. 1, the vehicle 10 is a one-box type passenger car, and the side portion (left side of the vehicle body) of the vehicle body 11 of the vehicle 10 is opened and closed to open and close the opening 12 formed in the side portion. A slide door 13 as a body is provided. The sliding door 13 slides in the direction indicated by the broken line arrow in the drawing, that is, in the front-rear direction of the vehicle body 11.

  As shown in FIG. 2, the slide door 13 is provided with a roller assembly 14, and the slide assembly 13 is guided by a guide rail 15 fixed to the side of the vehicle body 11. It can be opened and closed between a fully open position indicated by a solid line in the figure and a fully closed position indicated by a two-dot chain line in the figure. A curved portion 15a that curves toward the vehicle interior side (upward in the figure) is provided on the vehicle body front side of the guide rail 15, and the roller door 14 is guided by the curved portion 15a, whereby the slide door 13 is 11 is drawn into the inside of the vehicle body 11 and closed at the end of the closing operation so as to be in the same plane as the side surface of the vehicle 11.

  Here, although not shown, the roller assembly 14 is also provided in the upper and lower portions (upper portion and lower portion) of the front end portion of the slide door 13, and further, the upper and lower portions of the opening portion 12 of the vehicle body 11 corresponding thereto. Each is also provided with a guide rail. In this way, the sliding door 13 is supported at a total of three locations with respect to the vehicle body 11, and a stable opening / closing operation with respect to the vehicle body 11 is possible.

  As shown in FIG. 2, the vehicle body 11 is equipped with an opening / closing device 20 for automatically opening and closing the sliding door 13. The opening / closing device 20 includes a drive unit 21 that is fixed to the inside of the vehicle body 11 adjacent to a substantially central portion of the guide rail 15 in the vehicle longitudinal direction, and from the drive unit 21 toward the vehicle body front side and the rear side. Thus, a pair of cables 22a and 22b are drawn out. A cable 22a drawn from the drive unit 21 to the front side of the vehicle body is connected to the roller assembly 14 from the front side of the vehicle body via a reversing pulley 23a provided at the front end of the guide rail 15, and a cable 22b drawn to the rear side of the vehicle body is The roller assembly 14 is connected from the rear side of the vehicle body via a reversing pulley 23b provided at the rear end of the guide rail 15.

  The drive unit 21 drives the cables 22a and 22b. When the cables 22a and 22b are driven by the drive unit 21, the slide door 13 is connected to the front and rear cables 22a and 22b. It is designed to automatically open and close when pulled. That is, the switchgear 20 employs a so-called cable type switchgear.

  As shown in FIG. 3, the drive unit 21 has an electric motor 24 serving as a drive source thereof, and a speed reducer 25 connected to the electric motor 24, and the electric motor 24 is rotated at a predetermined speed by the speed reducer 25. The output speed is reduced to a number and output from the output shaft 26. As the electric motor 24, for example, a brushable DC motor or a brushless DC motor that can rotate in both forward and reverse directions can be used.

  A drum 27 formed in a substantially cylindrical shape is fixed to the output shaft 26, and the cables 22 a and 22 b are wound around the outer peripheral surface of the drum 27 a plurality of times. As a result, when the electric motor 24 rotates in the forward direction, the drum 27 rotates in the clockwise direction in the drawing, the cable 22a on the closing side is wound around the drum 27, and the sliding door 13 is pulled by the cable 22a to perform the closing operation. On the contrary, when the electric motor 24 rotates in the reverse direction, the drum 27 rotates counterclockwise in the drawing, the open cable 22b is wound around the drum 27, and the slide door 13 is pulled by the cable 22b to open. Operate.

  The speed reducer 25 includes an electromagnetic clutch (not shown). When the slide door 13 is manually opened and closed, the electromagnetic clutch is turned off and the power transmission path between the electric motor 24 and the output shaft 26 is set. Thus, the slide door 13 can be opened and closed manually with a light load. Here, although not shown, a tensioner mechanism is provided between the drum 27 and the slide door 13, and the tension of each cable 22a, 22b is always kept constant by this tensioner mechanism.

  An annular multipole magnet 28 having a large number of magnetic poles in the circumferential direction is fixed to the output shaft 26, and two Hall ICs 29 a and 29 b are provided in the vicinity of the multipole magnet 28 with a predetermined phase difference therebetween. Has been placed. When the output shaft 26 rotates, each Hall IC 29a, 29b outputs a pulse signal having a predetermined period proportional to the rotational speed of the output shaft 26.

  In order to control the rotation of the electric motor 24 in the forward and reverse directions, a control device (controller) 30 is electrically connected to the electric motor 24 via wiring. The control device 30 has a function as a so-called microcomputer having a microprocessor (CPU), a memory such as a ROM, a RAM, and the like (not shown) therein. The operation of the motor 24 is controlled.

  The Hall ICs 29a and 29b are electrically connected to the control device 30 via wiring, and the control device 30 is connected to the output shaft 26 based on a pulse signal having a predetermined period input from the Hall ICs 29a and 29b. The number of rotations, that is, the opening / closing speed of the slide door 13 is detected. Further, the control device 30 detects the rotation direction of the electric motor 24, that is, the moving direction of the slide door 13 based on the appearance timing of the pulse signals from the Hall ICs 29a and 29b, and the slide door 13 is further moved to the reference position. The opening / closing position of the slide door 13 is detected by integrating, that is, counting, the pulse signals from the Hall ICs 29a and 29b starting from the time when the position is (for example, the fully closed position).

  In order to command the opening / closing operation of the sliding door 13, the sliding door 13 is provided with a door handle 31 as an opening / closing switch. When the door handle 31 is operated by an operator such as an occupant, the door handle 31 A command signal (trigger signal) is input to the control device 30. That is, the control device 30 calculates the opening / closing position, opening / closing speed, and the like of the slide door 13 based on the input of the command signal from the door handle 31 using the control program stored in the memory, and the electric motor 24 from the calculation result. Rotation control (opening / closing control of the sliding door 13) is executed.

  For example, when the door handle 31 is operated when the slide door 13 is in the fully open state, the control device 30 receives the command signal from the door handle 31 and the slide door 13 is in the fully open position. Drive forward and move the slide door 13 in the fully closed direction. On the contrary, when the door handle 31 is operated when the slide door 13 is in the fully closed state, the control device 30 receives the command signal from the door handle 31 and the slide door 13 is in the fully closed position. Therefore, the electric motor 24 is driven in reverse to move the slide door 13 in the fully open direction.

  However, the door handle 31 as the opening / closing switch is not limited to the two-position switch that is switched to the ON-OFF state (two positions) as described above, but is, for example, three positions that are switched to the OPEN-OFF-CLOSE state (three positions). A switch or the like can also be employed.

  In order to detect the contact between the sliding door 13 and an obstacle (detected object) DA such as a baggage and the sandwiching of the obstacle DA by the sliding door 13 due to the contact, the front side of the sliding door 13, that is, the slide A pressure-sensitive sensor unit 40 is attached to the front end of the moving direction when the door 13 is closed. As shown in FIG. 2, the pressure sensor unit 40 is attached to a mounting stay 13a provided integrally with the slide door 13. The pressure sensor unit 40 includes a cable switch 50 and an elastic holder. 70.

  The cable-type switch 50 constituting the pressure-sensitive sensor unit 40 is electrically connected to the control device 30 through wiring as shown in FIG. 3, so that a short circuit signal generated at the time of elastic deformation of the cable-type switch 50 is generated. Input to the control device 30 enables detection of contact between the sliding door 13 and the obstacle DA and the sandwiching of the obstacle DA by the sliding door 13 due to the contact. When the control device 30 receives a short circuit signal from the cable switch 50, the control device 30 generates a warning sound from, for example, a piezoelectric sounder (not shown) and regulates the rotation control of the electric motor 24. .

  Next, the detailed structure of the pressure-sensitive sensor unit 40 will be described with reference to the drawings. 4 is an enlarged sectional view for explaining the structure of the pressure sensor unit, FIG. 5 is an enlarged sectional view for explaining the structure of the cable type switch, and FIG. 6 is an explanatory view for explaining the operating state of the cable type switch. ing.

  As shown in FIGS. 4 and 5, the cable-type switch 50 includes an inner electrode (first conductive member) 51 and an outer electrode (second conductive member) 52. The inner electrode 51 is formed in a solid cylindrical shape from a conductive material having flexibility such as ethylene-propylene-diene rubber (EPDM). The outer electrode 52 is formed in a hollow cylindrical shape by a conductive material having flexibility similar to that of the inner electrode 51.

  Three elastic insulators 53 made of an insulating material such as rubber are spirally provided between the inner electrode 51 and the outer electrode 52, and the inner electrode 51 and the outer electrode 52 are formed by each elastic insulator 53. A predetermined gap is formed between them. The elastic insulators 53 are provided at equal intervals in the circumferential direction, and the gap between the inner electrode 51 and the outer electrode 52 is made uniform in the longitudinal direction and the circumferential direction of the cable switch 50. In this way, by providing each elastic insulator 53 between the inner electrode 51 and the outer electrode 52, the inner electrode 51 and the outer electrode 52 are in a no-load state (non-deformed state) to the outer electrode 52. Are electrically insulated from each other (off state).

  An inner conductor (first conductor) 54 is inserted in the inner electrode 51 along the longitudinal direction thereof, and the inner conductor 54 is in contact with and electrically connected to the inner electrode 51. . Further, an inner coated conductor (second conductor) 55 is inserted in the inner electrode 51 so as to be aligned with the inner conductor 54 and electrically insulated from the inner conductor 54. The outer periphery of the coated conductor 55 is covered with a thin insulating film 56 made of an insulating material such as rubber. As a result, the inner coated conductor 55 is insulated from both the inner electrode 51 and the inner conductor 54. Both end sides of the inner conductor 54 and the inner coated conductor 55 are extended from both ends of the inner electrode 51, respectively.

  In the outer electrode 52, three outer conductors (third conductors) 57 are inserted along the longitudinal direction at equal intervals in the circumferential direction. Further, in the outer electrode 52, three outer coated conductors (fourth conductors) 58 provided so as to be aligned with the outer conductors 57 and electrically insulated from the outer conductors 57 are inserted. ing. These outer conductors 57 and outer sheathed conductors 58 are spirally provided so as to be positioned between the respective elastic insulators 53 as shown in FIG.

  Each outer conductor 57 is in contact with and electrically connected to the outer electrode 52. Further, the outer periphery of each outer coated conductor 58 is covered with a thin insulating film 59 made of an insulating material such as rubber similarly to the inner coated conductor 55, and each outer coated conductor 58 includes the outer electrode 52 and each outer conductor. 57 is insulated from both sides. Both end sides of each outer conducting wire 57 and each outer covering conducting wire 58 are extended from both end sides of the outer electrode 52.

  As shown in FIG. 5, one end side (the left side in the figure) of the inner conductor wire 54 and one end side of the inner coated conductor wire 55 are electrically connected to each other by a solder portion P1. Further, one end side (left side in the figure) of each outer conductive wire 57 and one end side of each outer coated conductive wire 58 are electrically connected by a solder part P2. FIG. 5 shows only one set of the outer conductor 57 and the outer sheathed conductor 58 provided in three sets along the circumferential direction of the outer electrode 52, and the solder portion P2 is similarly applied to the other two sets. Are electrically connected.

  A test resistor R as an electronic component is electrically connected between the other end of the inner conductor 54 and the other end of each outer conductor 57, and this test resistor R is a control board in the control device 30. (Not shown). Then, the control device 30 periodically detects the resistance value of the inspection resistance R, for example, when the slide door 13 is fully opened, thereby switching the state of the inner electrode 51 and the outer electrode 52, that is, switching such as a constant short circuit. It is possible to detect defects.

  Between the other end side of the inner coated conductor 55 and the other end side of each outer coated conductor 58, contact between the inner electrode 51 and the outer electrode 52 during the operation of the switching device 20 (see FIGS. 2 and 3), That is, the short circuit detection part (contact detection means) 60 which detects the short circuit with the inner side conducting wire 54 and each outer side conducting wire 57 is electrically connected. Similar to the inspection resistor R, the short-circuit detection unit 60 is provided on a control board in the control device 30.

  The short circuit detector 60 generates a short circuit signal by detecting a short circuit between the inner conductor 54 and each outer conductor 57 during operation of the switchgear 20. Based on the short-circuit signal output from the short-circuit detection unit 60, the control device 30 performs an emergency stop of the drive unit 21 (see FIGS. 2 and 3) or moves the slide door 13 in the fully open direction (reverse operation). It is like that.

  As shown in FIG. 4, the elastic holder 70 is formed in a predetermined shape by a flexible rubber or the like that is an insulator. The elastic holder 70 covers the periphery of the cable type switch 50 to protect the cable type switch 50 and also serves to hold the cable type switch 50 in a predetermined position of the slide door 13.

  The elastic holder 70 has an attachment portion 71 for attaching the cable type switch 50 to the attachment stay 13a. The attachment portion 71 is provided so as to extend across the left and right sides of the attachment stay 13a in the figure. A cored bar 72 is inserted into the mounting portion 71, thereby securing the mounting strength of the cable type switch 50 to the mounting stay 13a.

  The mounting portion 71 is integrally provided with a switch housing portion 73 having a hollow inside, and the cable type switch 50 is mounted in the switch housing portion 73. The switch housing portion 73 is provided with a predetermined amount offset from the axial center of the mounting portion 71 (axial center of the mounting stay 13a) to the vehicle interior side (right side in the figure). In this way, by providing the switch accommodating portion 73 with an offset, when the slide door 13 is pulled from the vicinity of the fully closed position to the vehicle interior side, the pressure-sensitive sensor unit 40 is provided with the pillar portion 11a of the vehicle body 11 (see FIG. 1). ) To avoid contact.

  As shown in FIG. 6, the distal end side (the upper side in the figure) of the switch housing portion 73 is formed thinner than the other portions of the elastic holder 70, so that the portion is easily elastically deformed. It has become. Therefore, even when the obstacle DA as the detected object comes into contact with the distal end side of the switch housing portion 73 with a relatively small external force F, the outer electrode 52 of the cable type switch 50 can be elastically deformed. Therefore, as shown in FIG. 6, the inner electrode 51 and the outer electrode 52 can be reliably brought into contact (ON state).

  Next, the assembly procedure of the pressure-sensitive sensor unit 40 configured as described above will be described with reference to the drawings. FIG. 7 is an explanatory diagram for explaining the procedure for assembling the cable type switch to the elastic holder.

  As shown in FIG. 7, the cable type switch 50 and the elastic holder 70 set to substantially the same length are prepared (preparation process).

  Next, one end side of the cable type switch 50, that is, the solder portion side 50a having the solder portion P1 and the solder portion P2 is made to face the end portion 70a of the elastic holder 70 (the lower end side in the mounting state on the slide door 13). Thereafter, as shown by the broken line arrow in the figure, the cable type switch 50 is inserted into the switch housing portion 73, and the insertion operation (attachment operation) is continued, whereby the cable type switch 50 is attached to the elastic holder 70. Is completed (mounting process).

  In addition, in order to make it easier to attach the cable type switch 50 to the switch housing portion 73, the inner peripheral surface of the switch housing portion 73 and the outer peripheral surface of the cable type switch 50 are lubricated with grease or the like (not shown). An agent may be applied.

  According to the cable-type switch 50 according to the first embodiment configured as described above, one end side of the inner conductor 54 and one end of the inner coated conductor 55 are electrically connected by the solder portion P1, and the outer conductor is connected. 57 and one end side of the outer coated conductor 58 are electrically connected by the solder portion P2, and an inspection resistor R is electrically connected between the other end side of the inner conductor 54 and the other end side of the outer conductor 57. In addition to the connection, the short-circuit detecting unit 60 is electrically connected between the other end side of the inner coated conductor 55 and the other end side of the outer coated conductor 58.

  Therefore, the inspection resistor R and the short-circuit detection unit 60 can be integrated on the other end side of each electrode 51, 52, and it is necessary to provide an electronic component (component) such as the inspection resistor R on one end side of each electrode 51, 52. Disappears. Since it is not necessary to worry about the twisting or bending of one end of each electrode 51, 52, it is possible to improve the handleability of the cable switch 50 with the inspection resistor R assembled. In addition, since there is no electronic component on one end side of each electrode 51, 52, the dimension in the short direction of each electrode 51, 52 can be reduced.

  Moreover, according to the cable type switch 50 which concerns on 1st Embodiment, each electrode 51,52 is hold | maintained at the elastic holder 70 which has the hollow switch accommodating part 73, and each electrode 51,52 is Since the solder part side 50a of each electrode 51, 52 is inserted into the elastic holder 70 by being inserted from the end part (end part 70a) of the switch housing part 73, the mounting property of each electrode 51, 52 to the elastic holder 70 is improved. Can be made.

  Furthermore, according to the cable-type switch 50 according to the first embodiment, the inspection resistor R and the short-circuit detection unit 60 are collectively provided on the control board in the control device 30, so that the slide door 13 of the cable-type switch 50 is provided. It is possible to improve the water coverage reliability by providing the control device 30 in the vehicle interior that is difficult to receive water.

  Next, a second embodiment of the present invention will be described in detail with reference to the drawings. FIGS. 8A and 8B are explanatory views for explaining a cable type switch according to the second embodiment. The same parts as those in the first embodiment described above are denoted by the same reference numerals, and detailed description thereof is omitted.

  As shown in FIG. 8A, the elastic holder 70 is provided with a switch accommodating portion 80 having a substantially rectangular cross section. In the switch housing portion 80, a cable type switch 81 formed in a shape substantially similar to the cross-sectional shape of the switch housing portion 80 is housed.

  The cable-type switch 81 includes an outer skin 82 formed of a flexible insulating material such as rubber, and the outer skin 82 is formed thin so as to be easily bent. A first electrode (first conductive member) 83 and a second electrode (second conductive member) 84 are provided in the outer skin 82 so as to extend in the longitudinal direction. The electrodes 83 and 84 are disposed opposite to each other in the outer skin 82 and are fixed to the inner side of the outer skin 82 with an adhesive or the like (not shown). In each of the electrodes 83 and 84, one side conductor (first conductor) 85, one side covered conductor (second conductor) 86, and the other side conductor (third conductor) 87, the other, extending in the axial direction thereof Side-coated conductors (fourth conductors) 88 are respectively inserted in a straight line.

  As shown in FIG. 8 (b), when the obstacle DA comes into contact with the distal end side (upper side in the figure) of the cable type switch 81 with the external force F, the switch housing portion 80 formed relatively thin is elastically deformed, Accordingly, the cable type switch 81 is elastically deformed so as to be crushed. Thereby, the 1st electrode 83 and the 2nd electrode 84 contact, and the one side conducting wire 85 and the other side conducting wire 87 are short-circuited.

  Also in the cable type switch 81 according to the second embodiment configured as described above, the same function and effect as those of the first embodiment described above can be achieved. In addition, according to the second embodiment, the elastic insulator 53 is not provided as compared with the first embodiment, and the conductors 85 to 88 are linearly inserted into the electrodes 83 and 84, respectively. Therefore, it becomes possible to improve moldability and reduce manufacturing costs.

  The present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the invention. For example, the connection relationship between the inspection resistor R and the short-circuit detection unit 60 can be reversed as compared to the above embodiments. That is, the inspection resistor R may be electrically connected between the respective covered conductors, and the short-circuit detecting unit 60 may be electrically connected between the respective uncovered conductors.
