TECHNICAL FIELD OF THE INVENTION
The present invention, For opening and closing the doorway formed on the side wall of the vehicle by sliding the door panelAutomatic sliding door deviceIn placeRelated.
[0002]
[Prior art]
In vehicles generally called wagons, vans, and recreational vehicles, a motor corresponding to a rear seat is operated by operating an operation switch provided near a driver's seat or at a predetermined position in the rear seat. There is a vehicle that employs a so-called automatic sliding door device that opens and closes a doorway formed on a vehicle body side wall by sliding a door panel back and forth along a vehicle body side wall portion by a driving force of a motor.
[0003]
As this kind of automatic sliding door device, there is also an automatic sliding door device provided with a pressure detecting device for detecting the foreign substance being caught or preventing the foreign substance from being caught when the door panel closes and moves.
[0004]
The pressure detection device applied to such an automatic sliding door device is long inside the outer skin along the front end of the door panel (that is, the end on the closing movement side) and along the longitudinal direction. A pressure sensor having a plurality of electrode wires is provided. In this pressure-sensitive sensor, when the outer skin portion is elastically deformed by receiving the pressing force, the electrode wires in the outer skin portion are curved and come into contact with each other with the elastic deformation of the outer skin portion, and the electrode wires are in contact with each other. That the pressing force has acted on the outer skin by detecting a change in electrical resistance at the time of contact, that is, the foreign object abuts on the front end of the door panel that closes and moves, and the pressing reaction force from the foreign object acts on the outer skin portion Is detected.
[0005]
[Problems to be solved by the invention]
By the way, the front end of the door panel is a hem (lined portion) of a plate-shaped outer panel like the plate-shaped inner panel constituting the door panel. It is folded back inside and fixed. In consideration of the appearance of the vehicle, the pressure-sensitive sensor described above supports a bracket or the like fixed to a portion on the rear end side of the door panel beyond the hem and the thickness direction of the inner panel is substantially in the front-rear direction of the vehicle. All or a part of the outer skin portion is attached via a member so as to protrude toward the vehicle front side from the end portion of the hem.
[0006]
Here, in the case of such a mounting mode of the pressure-sensitive sensor, as shown in FIG. 14, a sealing material for sealing the hem 222 is provided between the hem 222 of the door panel 220 and the outer skin 226 of the pressure-sensitive sensor 224. A gap 228 for applying (not shown) is provided. However, in rainy weather or the like, there is a high possibility that water droplets and the like enter the gap 228. Particularly, in a cold region or the like, there is a large possibility that snow enters the gap 228, and in this case, the snow that has entered the gap 228 solidifies between the outer skin portion 226 of the pressure-sensitive sensor 224 and the hem 222, and becomes ice. 230.
[0007]
In this state, the side of the outer skin 226 facing the hem 222 of the door panel 220 is supported by the ice 230, and the elasticity of the outer skin 226 when a pressing force acts on the outer skin 226 from the front (that is, from the direction of arrow B). Deformation is limited, and the ability to detect the pressing force is reduced.
[0008]
When the water droplets entering the gap 228 freeze, they naturally expand, but the ice 230 expanded inside the gap 228 presses the pressure-sensitive sensor 224 toward the inside of the vehicle. When the bracket 232 holding the outer skin 226 is bent by this pressing force, the amount of projection of the outer skin 226 with respect to the hem 222 changes, or the detection range of the pressure-sensitive sensor 224 (for example, with respect to the movement direction of the door panel 220). (Detection angle), and the ability to detect the pressing force is reduced.
[0009]
According to the present invention, in consideration of the above fact, it is possible to prevent a decrease in external force (pressing force) detection capability due to adhesion of ice or the like.Automatic sliding door device for vehiclesThe purpose is to obtain

The protector is formed in a tubular shape, a part of which protrudes substantially forward of the hem from the vehicle, and further, a sensor body is accommodated inside the protector.
[0013]
When the door panel is slid substantially forward of the vehicle to close the entrance, if a foreign object exists on the track of the door panel, the protector contacts the foreign object and presses the foreign object. Since the protector has lower rigidity than the outer skin portion of the sensor main body housed inside the protector, the protector is elastically deformed by the pressing reaction force from the foreign matter.
[0014]
Due to the elastic deformation of the protector, the outer skin portion of the inner sensor main body is elastically deformed, and the electrode wires provided inside the outer skin portion are bent and come into contact with each other to conduct. This makes it possible to detect the entrapment of foreign matter.
[0015]
On the other hand, a gap is formed between the hem of the door panel and the protector of the pressure-sensitive sensor, and a sealing material for sealing the hem is applied to the hem from the gap. Here, in the automatic sliding door device for a vehicle according to the present invention, the tip of the shielding member protruding from the protector is in contact with the hem, whereby the gap is closed.

[0021]
When the door panel is slid substantially forward of the vehicle to close the entrance, if a foreign object exists on the track of the door panel, the protector contacts the foreign object and presses the foreign object. Since the protector has lower rigidity than the outer skin portion of the sensor main body housed inside the protector, the protector is elastically deformed by the pressing reaction force from the foreign matter.

ProtectorHaFormed in a tube shape,Part of itProtrudes substantially forward of the vehicle from the hem, and further contains a sensor body inside.
[0029]
When the door panel is slid substantially forward of the vehicle to close the entrance, if a foreign object exists on the track of the door panel, the protector contacts the foreign object and presses the foreign object. Since the protector has lower rigidity than the outer skin portion of the sensor main body housed inside the protector, the protector is elastically deformed by the pressing reaction force from the foreign matter.
[0030]
Due to the elastic deformation of the protector, the outer skin portion of the inner sensor main body is elastically deformed, and the electrode wires provided inside the outer skin portion are bent and come into contact with each other to conduct. This makes it possible to detect the entrapment of foreign matter.
[0031]
On the other hand, a gap is formed between the hem of the door panel and the protector of the pressure-sensitive sensor, and a sealing material for sealing the hem is applied to the hem from the gap. Here, in the automatic sliding door device for a vehicle according to the present invention, the protectionOrThe tip of the shielding member protruding from the abutment is in contact with the hem, thereby closing the gap.

I have. The slide door driver 94 is connected to the battery 26 via a computer 96 as a determining means. For example, when the operation switch 98 provided near the driver's seat of the vehicle 14 is operated, the operation switch 98 at that time is turned on. A signal corresponding to the switch state is sent to the slide door driver 94, and the slide door motor 28 is driven forward or backward, or stopped.
[0052]
On the other hand, the automatic sliding door device 16 includes a position detecting device 100. The position detecting device 100 includes, for example, a disk-shaped slit disk in which slit holes are radially formed at predetermined angles along the circumferential direction, and rotates in conjunction with the rotation of the output shaft of the slide door motor 28, Counts the number of times that light emitted from the light emitting element and passed through the slit of the rotating slit disc is received by the light receiving element. By doing so, the number of rotations of the output shaft of the sliding door motor 28, that is, the sliding amount of the door panel 18 is detected.
[0053]
As shown in FIG. 6, the automatic sliding door device 16 includes a closer actuator 102 provided on the vehicle body 20. The closer actuator 102 includes a closer motor 104, and a pair of junctions (not shown) provided at an end of the door panel 18 in the closing movement direction side and an inner peripheral portion of the entrance 58 facing the same, respectively. When the door panel 18 slides until it is electrically connected to each other, and becomes a so-called half-door state, the closer motor 104 is energized to start driving to close the door panel 18 and determine the sliding amount at this time by a position detecting device. When the detection is made by 100, the computer 96 operates the slide door driver 94 to stop the power supply from the battery 26 to the slide door motor 28 and stop the slide door motor 28. When the closer motor 104 slides and closes the door panel 18 and the latch switch (not shown) of the closer actuator 102 detects this, the door panel 18 is locked via mechanical transmission means such as a link mechanism.
[0054]
(Configuration of pressure detection device 10)
Next, the configuration of the pressure detection device 10 will be described.
[0055]
As shown in FIGS. 7 and 8, the pressure detection device 10 includes a pressure-sensitive sensor 120 that is provided along an end of the door panel 18 on the closing movement side and that is elongated along the up-down direction of the vehicle 14. Have. As shown in FIGS. 1, 2, and 3, the pressure-sensitive sensor 120 is provided at the end of the door panel 18 on the closing movement direction side (that is, on the inner peripheral portion of the side wall 22 as the closing body, on the vehicle rear side). The hem (lined portion) 52 of the inner panel 54 and the outer panel 56, which is the opposite end facing the side facing the side, is disposed on the vehicle cabin interior side, and a part thereof is the tip of the hem 52, which is the opposite end. Projecting forward of the vehicle. Further, the pressure-sensitive sensor 120 includes an outer skin portion 124 which is formed in a long shape with an insulating elastic material such as rubber or a soft synthetic resin material and forms the sensor main body 122. 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.
[0056]
Further, inside the outer skin portion 124, an electrode wire 128 as an electrode formed as a flexible long cord by twisting a conductive thin wire such as a copper wire and covered with a conductive rubber, 130, 132 and 134 are provided. These electrode wires 128 to 134 constitute the sensor main body 122 and are spaced apart from each other via the cross hole 126 near the center of the cross hole 126 and spirally arranged along the cross hole 126 as shown in FIG. And is integrally fixed to the inner peripheral portion of the cross hole 126. 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 is elastically deformed to the 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 wire. Conducts by contacting the line 134. When the outer skin 124 is restored, the electrode wires 128 to 134 are also restored.
[0057]
As shown in the circuit diagram of FIG. 5, the electrode wire 128 and the electrode wire 132 are conductive at one end in the longitudinal direction, and the electrode wire 130 and the electrode wire 134 are also conductive at one end in the longitudinal direction. are doing. On the other hand, as shown in FIGS. 1 and 2, a connector 136 is arranged between the inner panel 54 and the outer panel 56 that constitute the door panel 18. As shown in the circuit diagram of FIG. 5, a resistor 138 is provided inside the connector 136. One end of the resistor 138 is electrically connected to the other end of the electrode line 130 in the longitudinal direction, and the other end of the resistor 138 is electrically connected to the other end of the electrode line 132 in the longitudinal direction. The line 130 and the electrode line 132 are electrically connected via the resistor 138.
[0058]
Further, inside the connector 136, one end in the longitudinal direction of a pair of conducting wires 142 and 144 of the lead wire 140 as a connecting means is accommodated and fixed to a terminal inside the connector 136. The other ends of the above-described electrode wires 128 and 134 in the longitudinal direction are fixed to the terminals to which the conductors 142 and 144 are fixed, and the conductors 142 and the electrode wires 128 are electrically connected. , The conductive wire 144 and the electrode wire 134 are electrically connected. The conducting wire 142 is directly or indirectly connected to the battery 26 via another connecting member (for convenience, the conducting wire 142 is directly connected to the battery 26 in the circuit diagram of FIG. 4). It is connected to the battery 26 via a current detecting element 146 that cuts off the circuit when a current of a predetermined value or more flows. That is, the current flowing from the electrode wire 128 to the electrode wire 134 via the electrode wire 130 and the electrode wire 132 normally flows via the resistor 138, but if the outer cover 124 is crushed temporarily, the electrode wire 128 or the electrode wire When the contact 132 is brought into contact with the electrode line 130 or the electrode line 134 to conduct and short-circuit, the current flows without passing through the resistor 138. For example, the current value changes if the current flows through this circuit at a constant voltage. . Therefore, by detecting a change in the current value at this time, it is possible to detect whether or not the outer cover 124 is crushed, that is, whether or not an external force acts on the outer cover 124.
[0059]
As shown in FIGS. 5 and 6, the current detecting element 146 is connected to the computer 96, and the current detecting element 146 has passed a predetermined value or more of current in the circuit, that is, the electrode wire 128 or When the current detection element 146 detects that the electrode wire 132 is in contact with the electrode wire 130 or the electrode wire 134 to conduct and short-circuit, the computer 96 operates the slide door driver 94 and the closer driver 110 to operate the slide door motor 28 and The closer motor 104 is driven to reverse.
[0060]
As shown in FIGS. 1 and 2, the sensor main body 122 having the above-described configuration includes a protector 148 formed of a long tube made of a synthetic resin material or a rubber material having a lower rigidity than the synthetic resin material forming the outer skin portion 124. It is kept inserted inside.
[0061]
As shown in FIG. 1, the protector 148 includes a concave holding portion 150 whose cross section opens toward the front side of the vehicle 14. The radius of curvature of the concave portion of the holding portion 150 corresponds to the radius of curvature of the outer diameter of the outer skin portion 124 described above, and is in contact with a portion of the outer skin portion 124 corresponding to the rear side of the vehicle 14. On the front side of the vehicle 14 of one of the holding portions 150, a concave flexible portion 152 opened toward the rear side of the vehicle 14 is continuously formed. The radius of curvature of the concave portion of the flexible portion 152 also corresponds to the radius of curvature of the outer diameter of the outer skin portion 124, and covers the portion of the outer peripheral portion of the outer skin portion 124 that is not in contact with the holding portion 150. Is in contact with That is, the flexible portion 152 and the holding portion 150 are formed in a long tube shape having an inner diameter corresponding to the outer diameter of the outer skin portion 124, and the sensor main body 122 is accommodated inside the tube.
[0062]
In addition, a silicon layer (not shown) as a cold-resistant layer is formed on the surface of the flexible portion 152 to prevent the flexible portion 152 from freezing and hardening when the temperature falls in winter or the like. . This silicon layer has a relatively low intermolecular force of constituent molecules, and has such physical characteristics. Therefore, the silicon layer itself generally has high cold resistance and is hard to be cured even at a low temperature.
[0063]
On the other hand, a mounting portion 154 is formed continuously on the opposite side of the flexible portion 152 of the holding portion 150. The mounting portion 154 is formed with a mounting groove 156 that opens toward the rear side of the vehicle 14 and is elongated along the longitudinal direction of the holding portion 150 and the flexible portion 152. It is attached to a bracket 170 as a support means provided near the portion.
[0064]
Further, a ring-shaped flange forming an engagement portion in a direction substantially orthogonal to the longitudinal direction of the protector 148 near the lower end of the protector 148 in a state where the pressure-sensitive sensor 120 is attached to the door panel 18. A portion 158 is formed. Further, a ring-shaped flange 160 substantially similar to the flange 158 constituting the engaging portion is formed from a position spaced a predetermined distance from the flange 158 along the longitudinal direction of the protector 148. An outer diameter dimension between the flange 158 and the flange 160 is a neck 162 having a smaller diameter than the flanges 158 and 160 and forming an engagement portion, and is substantially coaxial with the flanges 158 and 160.
[0065]
In addition, a seal portion 164 is formed on the axial end face of the flange 160 opposite to the neck 162. The outer diameter of the seal portion 164 is slightly larger than that of the flange 160, and is formed substantially coaxially with the flange 160.
[0066]
Further, as shown in FIGS. 1 and 2, a lip 166 as a shielding member protrudes from an outer peripheral portion of the flexible portion 152 of the protector 148 toward a direction approaching the hem 52. As shown in FIGS. 2 and 3, the lip 166 is formed continuously along the longitudinal direction of the protector 148, and the tip of the lip 166 contacts the hem 52 as shown in FIG. To apply a sealing material (not shown) for sealing the hem 52 between the hem 52 and the protector 148 (that is, for sealing between the inner panel 54 and the tip of the portion where the outer panel 56 is folded rearward). Is closed.
[0067]
Further, as shown in FIG. 1, the lip 166 is made of the same material as the flexible portion 152 and has the same elasticity as the flexible portion 152. Therefore, when an external force is applied to the lip 166, the lip 166 is elastically deformed so as to rotate around the base end of the lip 166 (that is, a portion connected to the flexible portion 152).
[0068]
On the surface of the lip 166, particularly the surface of the lip 166 on the moving direction side when the door panel 18 closes the entrance 58, the above-described silicon layer (not shown) as a cold-resistant layer is continuous from the flexible portion 152. It is formed.
[0069]
As shown in FIGS. 1 and 2, in the vicinity of the front end of the door panel 18 to which the pressure-sensitive sensor 120 having the above configuration is attached, a part of the vicinity of the front end of the inner panel 54 is once bent to the left of the vehicle 14. In this portion, the thickness direction of the inner panel 54 is along the front-back direction of the vehicle 14. Further, the left end of the bent portion extends toward the front side of the vehicle 14, and the front end of the outer panel 56 is integrated with the front end of the inner panel 54 by caulking. A bracket 170 is provided at a bent portion of the inner panel 54 (that is, a portion where the plate thickness direction is the front-back direction of the vehicle 14). The bracket 170 includes a flat fixing portion 172 elongated in the vertical direction of the inner panel 54. One end of the fixing portion 172 in the width direction is a support portion 174 bent toward the front side of the vehicle 14, and enters the inside of the mounting groove 156 of the mounting portion 154 described above, and its tip (front end) is It is in contact with the bottom of the mounting groove 156. The mounting portion 154 is supported by the supporting portion 174 by sandwiching the supporting portion 174 by its own elastic force, and is formed by the adhesive force of the adhesive applied to at least one of the supporting portion 174 and the inside of the mounting groove 156. It is fixed to the support part 174.
[0070]
On the other hand, as shown in FIGS. 1 and 2, a circular hole 176 is formed at the lower end of the bracket 170, and fastening means such as bolts penetrating the circular hole 176 and the hole formed in the inner panel 54. The lower end of the bracket 170 is fixed to the inner panel 54 by (all are not shown). Although not particularly shown, a through hole similar to the circular hole 176 is also formed near the upper end of the bracket 170, and the upper end of the bracket 170 is similarly fixed to the inner panel 54 by fastening means such as bolts.
[0071]
Above the circular hole 176, a bracket 170 is fixed to the inner panel 54, and projects toward the front side of the vehicle 14 to form a concave portion 178 having a concave shape toward the rear side. The recess 178 has a circular shape as a whole, and its depth dimension is slightly deeper than the thickness (length in the axial direction) of the flange 160, and the thickness of the seal section 164 is equal to the thickness of the flange 160. Shallower than the sum of the dimensions. A recess 180 is formed at the bottom of the recess 178 coaxially with the recess 178. The drawing hole 180 is slightly smaller than the outer diameter of the neck portion 162 so that the neck portion 162 can penetrate. Here, the axial dimension of the neck 162 is substantially the same as the thickness of the bracket 170 at the portion where the drawing hole 180 is formed. The portion 160 abuts, and the flange 158 abuts on the outer bottom of the recess 178. As described above, since the depth of the concave portion 178 is smaller than the sum of the thickness of the flange 160 and the thickness of the seal 164, when the neck 162 is penetrated through the drawing hole 180, the depth of the vehicle 14 The seal portion 164 protrudes from the surface of the bracket 170 on the side, but the bracket 170 is fixed to the inner panel 54 and the surface of the bracket 170 is aligned with the surface of the inner panel 54 so that the seal portion 164 crushes the inner panel 54. The seal portion 164 comes into close contact with the inner panel 54 while being pressed.
[0072]
1 and 2, when the bracket 170 is fixed to the inner panel 54, along the axial direction of the through hole 182 (that is, along the arrow A direction in FIGS. 1 to 3). The drawing hole 180 formed in the recess 178 overlaps (overlaps) with the through hole 182 formed in the inner panel 54. The inner diameter of the through hole 182 is slightly larger than the lower end portion of the protector 148 beyond the flange 160, and the lower end of the protector 148 can be sufficiently penetrated, and the protector 148 passes through the through hole 182. Thus, the protector 148 enters the inside of the door panel 18 (that is, between the inner panel 54 and the outer panel 56), and the electrode wires 128 to 134 drawn from the lower end of the protector 148 are connected to the connector 136.
[0073]
Further, as shown in FIGS. 1 and 2, near the lower end of the bracket 170, a notch 184 opened at one end in the width direction of the bracket 170 and communicated with the above-described drawing hole 180 is formed. The width of the notch 184 is smaller than the outer diameter of the neck 162, and is sufficient to allow the neck 162 to pass through the notch 184 with the outer diameter partially reduced by elastic deformation. ing. Therefore, in a state where the neck 162 penetrates (fits into) the drawing hole 180, the neck 162 (the protector 148) does not come out of the drawing hole 180 unless the neck 162 is contracted intentionally.
[0074]
(Operation and effect of the present embodiment)
Next, the operation and effect of the present embodiment will be described.
[0075]
When the operation switch 98 is closed with the door panel 18 slid to the rear side of the vehicle 14 to open the entrance 58, the computer 96 operates the slide door driver 94 of the slide door actuator 24 to cause the slide door driver 94 to operate. The slide door motor 28 is driven to slide the door panel 18 toward the front side of the vehicle 14 via the endless belt 36 and the center arm 50.
[0076]
If a foreign object is present on the sliding track of the door panel 18 when the door panel 18 slides forward to fully close the entrance 58, the end (front end) of the door panel 18 in the closing movement direction contacts the foreign object to remove the foreign object. Press. When the protector 148 and the outer sheath portion 124 are elastically deformed by the pressing reaction force from the foreign matter at this time, 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 to conduct and short-circuit. . As described above, at this time, the current flowing through the electric circuit including the electrode lines 128 to 134 (see FIG. 5) flows without passing through the resistor 138. Therefore, for example, if the current flows through this circuit at a constant voltage, The value changes, and the outer skin portion 124 detects the change in the current value at this time. When the outer cover 124 detects a change in the current value, the computer 96 operates the slide door driver 94 and the closer driver 110 to reversely drive the slide door motor 28 and the closer motor 104 to move the door panel 18 to the rear side of the vehicle 14. Slide. This can prevent foreign matter from being caught by the door panel 18.
[0077]
Next, an example of a method of attaching the pressure-sensitive sensor 120 to the door panel 18 in the pressure detecting device 10 will be described below.
[0078]
When attaching the pressure-sensitive sensor 120 to the door panel 18, first, the attachment groove 156 of the protector 148 containing the inside 122 is fitted into the support portion 174 of the bracket 170, and at least the inside of the attachment groove 156 and the support portion 174 are provided. The protector 148 is fixed to the support portion 174 with an adhesive applied to one of the two, and the neck portion 162 and its vicinity are pressed to reduce the outer diameter of the neck portion 162, and the neck portion is inserted into the drawing hole 180 from the cutout portion 184. 162 is inserted and penetrated. In this state, the connector 136 is connected to the electrode wires 128 to 134 drawn from the lower end of the protector 148, and the lower end of the protector 148 that has passed through the drawing hole 180 is penetrated into the through hole 182. Then, the bracket 170 is fixed to the inner panel 54.
[0079]
Here, as described above, since the depth of the recess 178 is smaller than the sum of the thickness of the flange 160 and the thickness of the seal 164, the vehicle is in a state where the neck 162 is penetrated through the drawing hole 180. The seal portion 164 protrudes from the surface of the bracket 170 on the rear side of the bracket 14. The bracket 170 is fixed to the inner panel 54 and the surface of the bracket 170 and the surface of the inner panel 54 are aligned to form the seal portion 164 on the inner panel 54. The seal portion 164 comes into close contact with the inner panel 54 while being pressed. Thus, the through hole 182 is sealed, and rainwater or the like does not enter the inside of the door panel 18 through the through hole 182. Moreover, in this state, the bracket 170 and the flanges 158 and 160 wrap (overlap) along the axial direction of the through hole 182 (that is, along the direction of arrow A in FIGS. Since the through holes 182 are hidden by 158 and 160, appearance (appearance) is also improved. Further, since the flange portion 158 is in close contact with the periphery of the drawing hole 180 of the bracket 170, the drawing hole 180 is hidden by the flange portion 158. Therefore, on the appearance, in the vicinity of the portion penetrating through the lead-in hole 180 of the protector 148, the protector 148 appears to be simply curved, and in this sense, the appearance (appearance) is also improved.
[0080]
In addition, the protector 148 passes through the recess 180 formed in the bracket 170 and the through hole 182 formed in the inner panel 54 inside the door panel 18 (that is, the inner Since the bracket 170 is drawn into the space between the panel 54 and the outer panel 56), except for the upper end portion, the bracket 170 can detect the pressure (that is, the pressing reaction force from the foreign matter) until it penetrates the drawing hole 180. Become. Therefore, there is little dead zone, and it is possible to detect foreign matter near the lower end of the door panel 18.
[0081]
Further, conventionally, a special sealing member such as a grommet was used to seal the hole formed in the inner panel 54 like the through hole 182. Since a special sealing member becomes unnecessary, it contributes to cost reduction.
[0082]
Meanwhile, in a cold region or the like, when raindrops, snow, and the like adhere to the vehicle 14, the raindrops, snow, and the like that have been frozen and adhered may become ice 190 as shown in FIG. 1. Here, in the pressure-sensitive sensor 120 of the pressure detecting device 10, the lip 166 is formed so as to protrude from the flexible portion 152 of the protector 148, and the tip of the lip 166 is in contact with the hem 52. In this case, the gap 168 is closed by the lip 166. Accordingly, raindrops, snow, and the like do not enter the gap 168 from the front side of the vehicle 14. Therefore, ice (see FIG. 14) formed by freezing of raindrops, snow, and the like entering the gap 168 covers the outer peripheral portion of the protector 148, and the pressing force detection ability of the pressure-sensitive sensor 120 is reduced. It is possible to prevent the pressure sensing sensor 120 from deteriorating the ability to detect the pressing force from foreign substances and changing the pressing force detection range due to the decrease or the deformation of the bracket 170 due to the expansion when the water freezes. For this reason, the automatic sliding door device 16 to which the present pressure detecting device 10 is applied can reliably prevent foreign matter from being caught even in a low-temperature atmosphere such as a cold region.
[0083]
Also, as shown in FIG. 1, raindrops, snow, and the like may adhere to the surface of the lip 166 on the vehicle forward side and freeze to form ice 190. Unlike ice formed so as to connect the outer periphery of the protector 148 and the hem 52 at 168, it is extremely thin. Therefore, the door panel 18 is easily cracked and peeled off from the lip 166 by light vibration when the door panel 18 slides or light impact when a foreign object comes into contact.
[0084]
Further, as shown in FIG. 1, the ice 190 attached to the lip 166 is naturally supported by the lip 166, and the ice formed so as to connect the outer peripheral portion of the protector 148 and the hem 52 by the gap 168 is removed from the protector 148. And the hem 52. Here, the surface area of the lip 166 on the vehicle front side is smaller than the sum of the respective surface areas of the protector 148 and the hem 52 at opposing portions, and the supporting portion for supporting the ice is small. Therefore, the ice 190 attached to the lip 166 peels off with a smaller impact than the ice formed in the gap 168.
[0085]
Further, as described above, the silicon layer is continuously formed on the surface of the lip 166 from the flexible portion 152 side, and the silicon layer has the physical property that the intermolecular force of the constituent molecules is relatively low. Therefore, it has high cold resistance and is hard to freeze itself. Therefore, even if raindrops or snow adheres to the surface of the lip 166 on which the silicon layer is formed, the lip 166 is unlikely to freeze.
[0086]
Further, since the lip 166 is made of the same material as the flexible portion 152, the lip 166 is formed if an external force required to elastically deform the flexible portion 152 acts directly on the lip 166 or indirectly through the flexible portion 152. Elastically deform. However, since the ice 190 attached to the lip 166 cannot follow the elastic deformation of the lip 166, the ice 190 peels off from the lip 166 when the lip 166 elastically deforms.
[0087]
In order to remove the ice formed in the gap 168, the ice must be scraped out of the gap 168. If it is given to protector 148 of 120, it will easily come off.
[0088]
As described above, even if the ice 190 is formed due to the attachment of raindrops, snow, or the like to the lip 166, the ice 190 can be removed very easily (that is, without any special removal operation). For this reason, maintenance for the adhesion of ice is easy, and the ability of the pressure-sensitive sensor 120 to detect the pressing force from foreign substances can be maintained.
[0089]
In the present embodiment, the lip 166 is formed so as to protrude from the flexible portion 152 of the protector 148. However, the lip 166 may be formed so as to protrude from the holding portion 150.No.
[0090]
Next, a second embodiment of the present invention will be described.
[0091]
FIG. 13 is a cross-sectional view illustrating a configuration of a pressure detection device 200 according to the second embodiment of the present invention. As shown in this figure, the pressure detection device 200 has a hem 52 with a weather strip 202 attached thereto. Although not shown in detail, the weather strip 202 is elongated along the vertical direction of the vehicle 14 (see FIGS. 7 and 8), and the end of the hem 52 is substantially aligned with the vertical direction of the vehicle 14. In the same manner. Further, the weather strip 202 is formed of rubber or a synthetic resin material having elasticity similar to that of rubber, and when the door panel 18 fully closes the entrance 58, the inner peripheral portion of the entrance 58 in this fully closed state. Of these, the elastic member is elastically deformed and closely adheres to a portion facing the hem 52 along the front-rear direction of the vehicle 14 to prevent infiltration of raindrops and the like from between the hem 52 and the inner peripheral portion of the entrance 58.
[0092]
Further, as shown in FIG. 13, a lip 204 as a shielding member is formed so as to protrude from the outer peripheral portion of the weather strip 202 so as to approach the protector 148 of the pressure-sensitive sensor 120. The lip 204 is formed continuously along the longitudinal direction of the weather strip 202, and the tip of the lip 204 abuts against the hem 52, closing the gap 168 between the hem 52 and the protector 148.
[0093]
Further, the lip 204 is made of the same material as the weather strip 202, and has the same elasticity as the weather strip 202. Therefore, when an external force is applied to the lip 204, the lip 204 is elastically deformed so as to rotate about the base end of the lip 204 (that is, the connection portion with the flexible portion 152).
[0094]
That is, in the pressure detecting device 10 according to the first embodiment, the lip 166 is formed on the flexible portion 152 of the protector 148, whereas in the present pressure detecting device 200, the lip 204 is formed on the weather strip 202. The configuration is different in that it is formed.
