Description

  The present invention relates to a pinch detection device for detecting a pinch of a foreign object in, for example, an automatic door or a power window device.

  The door that opens and closes the entrance / exit corresponding to the rear seat of a vehicle, called a wagon, van, or recreational vehicle, is automatically slid by sliding the door in the vehicle longitudinal direction by the driving force of the motor, thereby opening and closing the entrance / exit A door device is adopted. In addition, this type of automatic sliding door device is provided with a pinching detection device that detects the pinching of foreign matter between the edge of the entrance / exit (that is, the vehicle body) and the end of the door. An example of an automatic sliding door device to which the detection device is applied is disclosed in Patent Document 1 below.

  Such a pinch detection device includes a long pressure-sensitive sensor along the front end portion (that is, the end portion on the closing direction side) of the door panel. A plurality of electrode wires are provided inside the pressure sensitive sensor. These electrode wires are bent and come into contact with each other when the pressure sensitive sensor receives a pressing force and elastically deforms. When the electrode lines come into contact with each other, a change occurs in the resistance value of the electric circuit including the electrode lines.

  These electrode wires are directly or indirectly connected to a control means such as an ECU. When the electrode wires come into contact with each other and the resistance value of the electric circuit changes, the motor that drives the door panel by the control means. Is stopped or the motor is driven in reverse. This prevents foreign matter from being caught between the door panel and the edge of the entrance.

  Further, for example, as shown in FIG. 14, the pressure sensor 350 used in the pinching detection device as described above includes a detection portion 352 to which a pressing force from a foreign substance acts substantially, and the pressure sensor 350 as a door panel. And an assembling portion 354 for assembling directly or indirectly in the vicinity of the front end portion.

The assembly portion 354 is formed in a substantially rectangular cross section, and a detection portion 352 having a substantially circular cross section is continuous on one side of the rectangle. An assembly groove 356 is formed in the assembly portion 354. The assembly groove 356 opens at the end surface of the assembly portion 354 opposite to the detection portion 352 so that a bracket 358 formed by bending a metal plate or the like enters from the opening of the assembly groove 356. The pressure sensor 350 is assembled to the bracket 358. As described above, the bracket 358 to which the pressure sensor 350 is assembled is fixed to the door panel near the front end of the door panel by welding or screwing.

  Here, as shown in FIG. 14, when the pressure sensor 350 is assembled to the bracket 358, the end of the bracket 358 is assigned to the opening end of the assembly groove 356, and in this state, the assembly 354 is interposed. The pressure sensor 350 is pressed by the roller 360 from the opposite side of the bracket 358, that is, the detection portion 352 side, and the roller 360 is rolled in the longitudinal direction of the pressure sensor 350 while pressing the pressure sensor 350 against the bracket 358. Thus, the bracket 358 is inserted into the assembly groove 356.

  However, when the pressure sensor 350 is assembled to the bracket 358 in this way, the detection portion 352 is pressed by the roller 360. If the pressing force applied to the roller 360 (the force that presses the roller 360 against the detection portion 352) is excessive, the detection portion 352 is crushed, whereby the electrode wire 362 is displaced inside the detection portion 352, and the electrode wire There is a possibility that a problem such as slack in 362 may occur.

  Such a problem is that the electrode wires 362 are in contact with each other regardless of the pressing force from the foreign matter, or the electrode wires 362 are in contact with each other despite the pressing force from the foreign matter. Since they do not come into contact with each other, the pinch detection device, and thus the automatic sliding door device, may cause malfunction. For this reason, the pressure-sensitive sensor 350 needs to be assembled carefully, and it is difficult to improve the working efficiency.

  The pressure-sensitive sensor 120 includes a sensor main body 122 as a detection unit that is generally circular in cross section and formed in a long string shape. The sensor main body 122 includes an outer skin portion 124 formed in an elongated shape from an insulating elastic material such as rubber or a soft synthetic resin material. A cross hole 126 having a cross-shaped cross section is formed inside the outer skin portion 124 along the longitudinal direction of the outer skin portion 124. The cross hole 126 is gradually displaced around the center of the outer skin portion 124 along the longitudinal direction of the outer skin portion 124.

  In addition, a plurality of electrode wires are formed inside the outer skin portion 124 as flexible electrodes formed by twisting conductive thin wires such as copper wires, and are covered with conductive rubber. 128, 130, 132, and 134 are provided. As shown in FIG. 1, these electrode lines 128 to 134 are spirally arranged along the cross hole 126 in a state of being separated from each other via the cross hole 126 in the vicinity of the center of the cross hole 126. It is integrally fixed to the inner peripheral part.

  Therefore, the electrode wires 128 to 134 bend due to the elastic deformation of the outer skin portion 124. In particular, if the outer skin portion 124 elastically deforms to such an extent that the cross hole 126 is crushed, the electrode wire 128 or the electrode wire 132 becomes the electrode wire 130 or the electrode.

  One end of the connecting portion 184 is connected to the longitudinal center of the base portion 178 of the one metal core 176, and the other end is connected to the longitudinal center of the base portion 178 of the other metal core 176. As described above, the plurality of core bars 176 are integrally connected by the connecting portion 184.

  Further, as shown in FIGS. 1 and 4, the end surface of the attachment portion 162 opposite to the lead wire accommodating portion 156 is a guide surface 172 as a guide portion. The guide surface 172 is a plane generally parallel to the longitudinal direction of the mounting portion 162.

  Further, a pressed surface 174 is formed on the mounting portion 162. The pressed surface 174 is formed on the inner side in the vehicle width direction than the recess 150 and on the side opposite to the opening end of the mounting groove 164.

  The pressed surface 174 is a plane that is substantially perpendicular to both the mounting portion 162 and the guide surface 172, that is, a plane that faces the assembly direction when the sensor support portion 168 enters the inside of the mounting groove 164. 162 is formed continuously in the longitudinal direction.

<Operation and Effect of First Reference Example >
Next, the operation and effect of this reference example will be described.

  First, a method of assembling the pressure-sensitive sensor 120 to the bracket 166, its operation, and effects will be described.

(Assembly method of pressure-sensitive sensor 120 and configuration of pressure roller 190)
When the pressure sensor 120 is assembled to the bracket 166, a pressure roller 190 is used. As shown in FIGS. 1 to 3, the pressure roller 190 includes a roller body 192. The roller body 192 is formed in a disk shape whose axial dimension is about the width of the pressed surface 174 and whose outer diameter dimension is constant along the axial direction. A flange portion 194 is provided on one end surface in the axial direction of the roller body 192. The flange portion 194 has a disk shape larger in diameter and thinner than the roller main body 192 and is formed coaxially with the roller main body 192.

  A support shaft 196 is disposed so as to pass through the axial center portions of the roller body 192 and the flange portion 194, and the roller body 192 and the flange portion 194 are rotatably supported by the support shaft 196. Both ends of the support shaft 196 are bent toward one side in the radial direction of the roller body 192, and a grip portion (not shown) is attached to the tip end side.

  When the pressure-sensitive sensor 120 is assembled to the bracket 166, first, the tip end portion of the sensor support portion 168 of the bracket 166 is applied to the opening end of the mounting groove 164. In this state, the pressed surface 174 is pressed to enter the sensor support portion 168, and the mounting portion 162 (that is, the pressure sensor 120) is temporarily fixed to the sensor support portion 168.

  Next, at one end in the longitudinal direction of the mounting portion 162, the end surface on the roller body 192 side of the flange portion 194 of the pressure roller 190 is brought into contact with the mounting portion 162, and the outer peripheral surface of the roller body 192 is pressed against the pressed surface. 174. In this state, the pressure roller 190 is pressed toward the pressed surface 174 (see FIG. 2).

  As a result, the sensor support 168 expands the mounting groove 164 against the elasticity of the cored bar 176 at one end in the longitudinal direction of the mounting part 162, and the tip of the sensor support 168 extends to the inner bottom of the mounting groove 164. The sensor support portion 168 enters the mounting groove 164 until it abuts.

  Next, with the pressing force applied to the pressure roller 190 as described above, the pressure roller 190 is further pressed to the other end in the longitudinal direction of the mounting portion 162 to roll the roller body 192 and the flange portion 194. Even in this state, the application of the pressing force to the pressed surface 174 is continued.

  For this reason, the sensor support portion 168 enters the mounting groove 164 until the tip of the sensor support portion 168 contacts the inner bottom portion of the mounting groove 164 sequentially and continuously toward the other end in the longitudinal direction of the mounting portion 162. Thereby, as shown in FIG. 3, the pressure-sensitive sensor 120 is assembled to the bracket 166. In this state, the holding piece 170 holds the sensor support portion 168 by the elasticity of the cored bar 176, and the pressure sensor 120 is supported by the bracket 166.

Here, in this reference example , a mounting portion 162 is formed on the side opposite to the hem 52 via the lead wire accommodating portion 156. The lead wire accommodating portion 156 is formed substantially on the vehicle rear side of the concave portion 150 and the flexible portion 152. Therefore, the mounting portion 162 is offset with respect to the recess 150 and the flexible portion 152 in a direction inclined substantially toward the vehicle rear side with respect to the vehicle interior side along the vehicle width direction (or the thickness direction of the door panel 18). ing.

  Further, as described above, the mounting groove 164 is opened substantially toward the vehicle rear side. For this reason, the assembly direction when the sensor support portion 168 is inserted into the attachment groove 164 is substantially the vehicle front-rear direction.

  Therefore, the mounting portion 162 (mounting groove 164) is in the vehicle width direction (or the thickness direction of the door panel 18) with respect to the mounting direction of the pressure-sensitive sensor 120 to the bracket 166 with respect to the concave portion 150 and the flexible portion 152. It can also be understood that it is offset in an inclined direction.

  Since the attachment portion 162 (attachment groove 164) is offset with respect to the recess 150 and the flexible portion 152 in this way, when the pressure-sensitive sensor 120 is assembled to the bracket 166, the pressure roller 190 presses the attachment portion 162. The surface 174 can be directly pressed, and the pressing force from the pressure roller 190 is not applied to the concave portion 150 and the flexible portion 152. Accordingly, it is possible to prevent peeling or disconnection of the electrode wires 128 to 134 from the outer skin portion 124 caused by the pressing force from the pressure roller 190 acting on the concave portion 150 and the flexible portion 152 and thus the sensor main body 122.

  Further, as described above, when the pressure-sensitive sensor 120 is assembled to the bracket 166, the pressed surface 174 of the mounting portion 162 is pressed by the pressure roller 190 in the mounting direction (that is, the opening direction of the mounting groove 164). .

  Here, since the pressed surface 174 faces the direction opposite to the opening direction of the mounting groove 164 (that is, the side opposite to the assembly direction), the direction of the pressing force when pressing the pressed surface 174 is attached. It is easy to face in the opening direction of the groove 164. Thus, when the pressed surface 174 is pressed by the pressure roller 190, a pressing force is applied to the pressed surface 174 accurately in the assembling direction, and the sensor support portion 168 is easily and reliably attached to the mounting groove 164. The pressure sensor 120 can be assembled to the bracket 166.

  On the other hand, depending on the design of the vehicle 14, the upper side and the lower side of the hem 52 may be curved inward in the vehicle width direction. In such a case, when the concave portion 150 and the flexible portion 152 of the pressure-sensitive sensor 120 are arranged as close to the hem 52 as possible, the sensor support portion 168 of the bracket 166 is curved along the hem 52, and further, the pressure-sensitive sensor Sensor 120 must be curved.

Here, the connecting portion 184 embedded in the mounting portion 162 is substantially rod-shaped (in the present embodiment , a rectangular bar shape) that is elongated along the longitudinal direction of the mounting portion 162 or along the longitudinal direction of the mounting portion 162. It is formed in a plate shape with sufficiently short dimensions. Therefore, the mounting portion 162 can be appropriately bent or bent around an axis whose axial direction is the direction intersecting the longitudinal direction.

  Moreover, the plurality of metal cores 176 embedded in the attachment portion 162 are provided at predetermined intervals along the longitudinal direction of the connecting portion 184 (that is, the plurality of metal cores 176 are provided in the longitudinal direction of the connecting portion 184). Are spaced apart from each other by a predetermined distance). Therefore, even if the mounting portion 162 is bent or bent, the adjacent core bars 176 do not interfere with each other. For this reason, the attachment part 162 can be easily bent or bent.

  Thus, by deforming the connecting portion 184, the pressure-sensitive sensor 120 can be appropriately curved. As a result, even if the hem 52 is curved, the pressure-sensitive sensor 120 conforms to the shape of the hem 52. The concave portion 150 and the flexible portion 152 can be provided in a state of being close to the hem 52.

(Characteristic action and effect of the pinch detection device 10)
For example, when the computer 96 operates the slide door driver 94 by operating the operation switch 98 and the slide door motor 28 is energized, the door panel 18 that has opened the entrance 58 is closed (that is, the door panel). 18 slides substantially forward of the vehicle).

  In this way, when a foreign object exists on the slide track of the door panel 18 while the door panel 18 is in the closed movement state, the end (front end) in the closing direction of the door panel 18 contacts the foreign object and presses the foreign object. To do.

  Here, in the pinching detection device 10, the flexible portion 152 of the pressure-sensitive sensor 120 protrudes substantially forward of the vehicle from the tip of the hem 52. For this reason, before a foreign object contacts the front-end | tip of hem 52, a foreign object contacts the flexible part 152, and the flexible part 152 presses a foreign object.

  Thus, when the flexible part 152 presses the foreign object, a pressing reaction force according to the pressing force applied to the foreign object by the flexible part 152 is applied to the flexible part 152 from the foreign object. Here, the flexible portion 152 is formed of a material that is more flexible than the outer skin portion 124. For this reason, when a pressing reaction force from a foreign substance is applied to the flexible portion 152, the flexible portion 152 easily deforms and transmits the pressing reaction force to the inner skin portion 124.

  Further, the recess 150 located in the direction of the pressing reaction force with respect to the outer skin portion 124 (that is, substantially on the vehicle rear side) has sufficiently higher rigidity than the rigidity of the outer skin portion 124. For this reason, even if the outer skin portion 124 to which the pressing reaction force is indirectly applied tends to move substantially toward the vehicle rear side, it is supported from the substantially vehicle rear side by the concave portion 150, thereby restricting the movement of the skin portion 124. . In this way, the movement of the outer skin portion 124 is restricted.

  As described above, in the pressure-sensitive sensor 120, the pressing reaction force received by the flexible portion 152 from the foreign matter is easily and quickly transmitted to the outer skin portion 124, and the outer skin portion 124 is elastically deformed quickly and reliably by the pressing reaction force. It is done.

  The outer skin portion 124 is elastically deformed, so that the electrode wire 128 or the electrode wire 132 in the outer skin portion 124 comes into contact with the electrode wire 130 or the electrode wire 134 and is short-circuited.

  When the electrode wire 128 or the electrode wire 132 is brought into contact with the electrode wire 130 or the electrode wire 134 to be conductive and short-circuited to increase the current flowing through the electric circuit shown in FIG. 6, a predetermined detection signal is output from the current detection element 146. Is done. When the predetermined detection signal is input to the computer 96, the sliding door motor 28 and the closer motor 104 are driven in reverse. As a result, the door panel 18 is slid toward the rear side of the vehicle 14, and foreign matter can be prevented from being caught by the door panel 18.

  Here, as described above, in the pinching detection device 10, the foreign matter comes into contact with the flexible portion 152 before the foreign matter comes into contact with the tip of the hem 52. Therefore, the foreign matter can be detected by the pressure sensor 120 before the foreign matter is completely sandwiched between the door panel 18 and the entrance 58, and the foreign matter can be quickly eliminated.

  In addition, the concave portion 150 and the flexible portion 152 constituting the detection portion protrude beyond the pressed surface 174 toward the front side of the door panel 18. For this reason, when the foreign object is to be caught, the foreign object reliably contacts the flexible portion 152 without being interfered with the pressed surface 174. Thereby, the foreign substance can be reliably detected by the pressure sensor 120 and the foreign object can be quickly caught.

  Further, as described above, the pressing reaction force received by the flexible portion 152 from the foreign matter is easily and quickly transmitted to the outer skin portion 124, and the outer skin portion 124 is quickly and surely elastically deformed by this pressing reaction force. Also by this, the foreign substance can be detected quickly by the pressure sensor 120, and the foreign object can be quickly caught.

  Furthermore, in the case of a foreign object having a short length across the entrance / exit 58, if the clearance between the hem 52 and the flexible part 152 is large, the foreign object may not reach the flexible part 152 even if the foreign object contacts the tip of the hem 52. There is sex. Here, in the pinch detection device 10 as described above, since the gap between the flexible portion 152 and the hem 52 can be reduced, even a foreign object having a short length crossing the entrance / exit 58 can reach the flexible portion 152. Thus, even a small foreign object can be detected.

<First Embodiment>
Next, a first embodiment of the present invention will be described. In the description of the present embodiment, the same reference numerals are given to the same parts as those in the first reference example, and the detailed description thereof is omitted.

FIG. 9 is a perspective view showing the configuration of the pressure-sensitive sensor 212 of the pinch detection device 210 according to the first embodiment of the present invention. FIG. 10 shows the pressure-sensitive sensor 212 of the pinch detection device 210. The configuration is shown by a cross-sectional view.

  As shown in these drawings, the pressure-sensitive sensor 212 of the pinch detection device 210 includes a cored bar 214 instead of the cored bar 176. The cored bar 214 is the same as the cored bar 176 in that it includes a base 178 and a leg 182, but the cored bar 214 does not include the leg 180, but instead includes a leg 218.

  The leg portion 218 is shorter than the leg portions 180 and 182, and the tip thereof is located between the recess 150 and the lead wire accommodating portion 156. A support leg 220 as a support is formed from the tip of the leg 218. The support leg 220 extends from the tip of the leg portion 218 to the opposite side of the mounting groove 164 and is interposed between the lead wire accommodating portion 156 and the recess 150.

  As shown in FIG. 11, the cored bar 214 having the above configuration is provided in plural along the longitudinal direction of the mounting portion 162 in the same manner as the cored bar 176, and the cored bar 214 is connected between the cored bars 214. The parts 184 are integrally connected.

The pinching detection device 210 including the pressure sensor 212 having the cored bar 214 having the above-described configuration has a cored bar 214 having a leg 218 and a support leg 220 instead of the cored bar 176 having the leg 180. Since the configuration is basically the same as that of the pressure-sensitive sensor 120, the same operation as that of the first reference example is basically performed, and the same effect can be obtained.

  In the present embodiment, as described above, the support leg 220 is interposed between the lead wire accommodating portion 156 and the recess 150. For this reason, when the outer skin portion 124 and the concave portion 150 try to move substantially toward the rear side of the vehicle due to the pressing reaction force of the foreign matter when the foreign matter is sandwiched, the support leg 220 regulates the outer skin portion 124 and the concave portion 150 by its rigidity, The part 124 and the recessed part 150 are supported. Thus, by restricting the movement of the outer skin portion 124, the outer skin portion 124 that has received the pressing reaction force is quickly and reliably elastically deformed.

As described above, in the present embodiment, the support leg 220 can ensure the rigidity for resisting the pressing reaction force from the foreign matter. For this reason, unlike the first reference example , the rigidity of the recess 150 can be set low. As a result, the degree of freedom in selecting the material of the concave portion 150, the attachment portion 162 and the lead wire accommodating portion 156 made of the same material as the concave portion 150 is improved, and the cost can be reduced.

  In the present embodiment, the support leg 220 as a support is formed on the cored bar 214, but the cored bar 214 and the support may be formed separately (in other words, the cored bar 176 and a support body may be embedded between the attachment portion 162 and the lead wire accommodating portion 156 and the recess 150, respectively).

< Second Reference Example >
Next, a second reference example will be described.

FIG. 12 is a perspective view showing the configuration of the main part of the pinch detection device 230 according to the second reference example , and FIG. 13 is a cross-sectional view showing the configuration of the main part of the pinch detection device 230. Yes.

  As shown in these drawings, the pinch detection device 230 includes a bracket 232 instead of the bracket 166. The bracket 232 includes a fixing portion 234.

  Unlike the fixed portion 169, the fixed portion 234 is formed in a plate shape that is bent at a substantially right angle in the intermediate portion in the width direction, and a portion of the fixed portion 234 whose width direction is substantially along the vehicle width direction is a bolt or a rivet. It is integrally fixed to the inner panel 54 of the door panel 18 by fastening means or welding. The bracket 232 includes a support plate 236 as a support.

  The support plate 236 is formed in a plate shape having a width direction substantially along the vehicle width direction. One end in the width direction of the support plate 236 is continuous with the base end of the sensor support 168. On the other hand, the other end in the width direction of the support plate 236 is continuous with the fixed portion 234.

In other words, the bracket 166 in the first reference example has a shape in which a flat plate is bent in a substantially L-shaped cross section, whereas in this reference example , two L-shapes are formed by bending the flat plate in a zigzag manner. It is formed in the cross-sectional shape drawn.

  An end surface of the bracket 232 facing the vehicle front side of the support plate 236 is in contact with an end portion of the attachment portion 162 on the substantially vehicle rear side (that is, an end portion of the attachment portion 162 on the opening side of the attachment groove 164). .

Or more aspects of the bracket 232 detector 230 entrapment including Umate configured to, because except with alternative bracket 232 to the bracket 166 has the same configuration as the detector device 10 basically entrapment, the basically The same effect as that of the first reference example can be obtained, and the same effect can be obtained.

Further, in this reference example , as described above, the end surface of the support plate 236 constituting the bracket 232 is in contact with the substantially vehicle rear side end portion of the mounting portion 162 of the protector 148. For this reason, when the outer skin portion 124, the concave portion 150, and the mounting portion 162 are moved substantially to the rear side of the vehicle by the pressing reaction force of the foreign matter when the foreign matter is sandwiched, the support plate 236 (that is, the bracket 232) is attached by its rigidity. The portion 162 is regulated and the outer skin portion 124 and the concave portion 150 are supported via the attachment portion 162.

  Thus, by restricting the movement of the outer skin portion 124, the outer skin portion 124 that has received the pressing reaction force is quickly and reliably elastically deformed.

Thus, in the present reference example , the support plate 236 can ensure rigidity for resisting the pressing reaction force from the foreign matter. For this reason, unlike the first reference example , the rigidity of the recess 150 can be set low. As a result, the degree of freedom in selecting the material of the concave portion 150, the attachment portion 162 and the lead wire accommodating portion 156 made of the same material as the concave portion 150 is improved, and the cost can be reduced.

In each of the above reference examples and embodiments, the protector 148 (that is, the pressure sensitive sensors 120 and 212) is attached to the door panel 18 via the brackets 166 and 232, but the protector 148 ( that may be applied to the structure for assembling the pressure sensor 120,212) directly.

Moreover, although each said reference example and embodiment were the structures which provided the pressure sensitive sensors 120 and 212 in the door panel 18, the pressure sensitive sensor is provided in the part facing the hem 52 among the edges of the entrance / exit 58. 120 and 212 may be provided.

Furthermore, the reference examples and the embodiment described above was configured to have applied to automatic sliding door system for opening and closing the entrance 58 of the vehicle both 14. However, the present invention is not limited to such an automatic sliding door device.

For example, in the case of the vehicle 14, the present invention may be applied to an automatic door device in which the door panel rotates in the axial direction approximately in the vertical direction of the vehicle by the driving force of the motor. and substantially back door of the vehicle vertical direction in the axial direction may be applied to an automatic back door apparatus for opening and closing an opening formed in the rear end of the vehicle rotates.

  Furthermore, the present invention may be applied for detecting foreign object pinching in an automatic opening / closing device such as an automatic door of a railway vehicle or building.
