[0002]

2. Description of the Related Art In vehicles such as wagons and vans, there is an automatic sliding door device which opens and closes by sliding a door panel along the longitudinal direction of the vehicle by the driving force of a driving means such as a motor.

Such an automatic sliding door device is disclosed in Japanese Patent Application Laid-Open No. 61-248310 and US Pat. No. 4,762,970 when foreign matter is caught between a door panel and a vehicle body during closing movement. An automatic sliding door device has been devised which detects a jamming state by a pressure-sensitive sensor as described above, and for example, includes a jamming detecting device for stopping sliding of the door panel or re-opening the door panel.

Japanese Patent Application Laid-Open No. 61-248310 and US Pat.
Any of the pressure-sensitive sensors disclosed in, for example, Japanese Patent No. 0234418 and the like, is a rubber material or a flexible synthetic resin material which can be elastically deformed by a reaction force from the foreign material when the foreign material is sandwiched between the door panel and the vehicle body. And a plurality of electrodes arranged apart from each other inside the outer skin portion are brought into contact with each other due to elastic deformation of the outer skin portion to conduct electricity.

A power supply line such as a lead wire is electrically connected to the electrode of such a pressure-sensitive sensor. The power supply line passes through the end of the door panel in the moving direction side, passes through the inside of the door panel, and is connected to a power supply (battery) through sliding contacts and the like. A part of the power supply line is provided with a current detection element that detects a change in the value of the current flowing in the electric circuit, and detects a change in the current value when the electrodes of the pressure-sensitive sensors come into contact with each other and conduct. In the automatic sliding door device, a signal is transmitted to a control means such as a computer or a control circuit for controlling a driving means for driving the door panel of the automatic sliding door device, and the control means controls the motor to stop the sliding movement of the door panel, or , And the door panel is moved again.

By the way, as described above, the electrodes of the pressure-sensitive sensor must be connected to the power supply line at the terminal. However, in the pressure-sensitive sensor disclosed in Japanese Patent Application Laid-Open No. 61-248310, the outer skin is cut off, and the power supply line is fixed to the electrode while being electrically connected to the electrode by soldering.
This cut-off portion is filled with an insulating synthetic resin material, etc., so that the power supply line is exposed at a position visible to the occupants entering and exiting the vehicle through the doorway closed by the door panel. Many costs are high.

On the other hand, in the pressure-sensitive sensor disclosed in US Pat. No. 5,023,418, since the power supply line is buried in the mountain strip, the periphery of the outer conductor (electrode) is made conductive and the power supply line is electrically connected. The surroundings must be insulating and difficult to manufacture.

The door panel 14 is guided to a predetermined position where the lock can be performed.

That is, in the vehicle 12, the slide of the door panel 14 (that is, the opening and closing movement) is basically performed by the slide motor 39 (slide actuator 34).
However, the door motor 14 is moved by the closer motor 59 (closer actuator 56) only immediately before the door panel 14 is fully closed.

(Structure of Pressure Sensing Sensor 60) FIG. 1 is an enlarged perspective view showing the vicinity of the front end of the door panel 14, and FIG. 2 is a sectional view taken along line 2-2 in FIG. It is shown. As shown in FIG. 1, near the front end of the door panel 14, there is provided a pressure-sensitive sensor 60, which is a longitudinal direction along the vertical direction of the vehicle 12 and constitutes the pressure detecting device 10. The pressure-sensitive sensor 60 has an outer skin portion 62 formed of an elastic material having an insulating property such as rubber or a soft synthetic resin material. A cross hole 64 having a cross-shaped cross section is formed inside the outer skin portion 62 along the longitudinal direction of the outer skin portion 62. The cross hole 64 is gradually displaced around the center of the outer skin portion 62 along the longitudinal direction of the outer skin portion 62. An electrode 6 which is formed into a flexible long cord by bringing a conductive thin wire such as a copper wire close to the inside of the outer skin portion 62 and forms a sensor main body together with the outer skin portion 62.
6, 68, 70, 72 are provided. These electrodes 66 to 72 are separated from each other via the cross hole 64 near the center of the cross hole 64 and are spirally arranged along the cross hole 64, and are integrally fixed to the inner peripheral portion of the cross hole 64. I have. Therefore, when the outer skin portion 64 is elastically deformed, the electrodes 66 to
72 is bent, and in particular, the outer skin 6

However, only the electrode 72 is connected to a power supply via an ammeter or a current detecting element 84 which cuts off the circuit when a current of a predetermined value or more flows. That is, the current flowing from the electrode 66 to the electrode 72 via the electrodes 68 and 70 normally flows via the resistor 80, but if the outer cover 62 is crushed and the electrode 66 or the electrode 70 is When the current flows through the circuit at a constant voltage, the current value changes, for example, if the current flows through the circuit without contacting the resistor 80 when the current flows through the resistor 80 and short-circuits. Therefore, if a change in the current value at this time is detected, it is determined whether or not the outer skin portion 62 has been crushed, that is,
It can be detected whether or not an external force has acted on the outer skin portion 62. Further, as shown in FIG. 4, the current detecting element 84 is connected to the computer 36, and when the current detecting element 84 detects that a current of a predetermined value or more flows in the circuit, that is, the electrode 66 or the electrode When the current detecting element 84 detects that the electrode 70 or the electrode 70 is in contact with the electrode 68 or the electrode 72 and is short-circuited, the computer 36 operates the slide driver 38 and the closer driver 56 to operate the slide motor 39.

(Operation and Effect of the First Embodiment)
The operation and effect of the present embodiment will be described.

In the vehicle 12, the door panel 14 has the opening 20.
When the operation switch 52 is operated and the slide actuator 34 is driven in a state where the is closed, the drive roller 30 rotates to rotate the endless belt 32, and the endless belt 32 pulls the bracket 22 to the rear side of the vehicle 12. When the bracket 22 is pulled, the roller 24 moves to the guide rail 26.
, The roller (not shown) of the operation switch 42 also moves along the guide rail 48. As a result, the door panel 14 slides rearward of the vehicle 12. Here, since the front ends of the vehicle body 16 and the guide rail 48 are curved inward in the vehicle width direction of the vehicle 12, the rollers 24 of the bracket 22 and the rollers of the bracket 46 temporarily move in the vehicle width direction when moving rearward. Move outward. The outward movement in the vehicle width direction causes the door panel 14
Is located outside the vehicle body 16 and can slide rearward along the vehicle body 16 in this state.

On the other hand, if the slide switch 34 is driven by operating the operation switch 52 in a state where the door panel 14 is moved and the opening 20 is opened, the drive roller is moved in the direction opposite to the opening direction of the door panel 14. 30 rotates and the endless belt 32 rotates, and the endless belt 32 pulls the bracket 22 forward of the vehicle 12. As a result, the door panel 14 slides forward of the vehicle 12. Then, the door panel 14 moves inward in the vehicle width direction of the vehicle 12 along the curves of the vehicle body 16 and the guide rails 48,
When the rotation position detecting means 44 detects the rotation of the slide motor 39 of the slide actuator 34 until the door panel 14 is in a state immediately before completely closing the opening 20, the drive of the closer motor 59 of the closer actuator 56 is started. The closer motor 59 activates a lock mechanism for locking the door panel 14 with the opening 20 fully closed, and guides the door panel 14 to a position where the lock mechanism can lock the door panel 14. Thus, when the door panel 14 fully closes the opening 20, the locking mechanism locks the door panel 14 and restricts the movement of the door panel 14 in the opening direction without a predetermined opening operation.

During the above-described closing drive, when the front end of the door panel 14 comes into contact with an obstacle on the path of the closing movement of the door panel 14 and presses the obstacle, first, a reaction force from the obstacle causes a pressing reaction. The flexible portion 94 of the protector 90 elastically deforms, and then the outer skin portion 62 of the pressure-sensitive sensor 60 elastically deforms. Thereby, the electrodes 66 to 72 inside the outer skin portion 62 are deformed and come into contact with each other. Electrode 66 or electrode 7
When 0 is short-circuited by contact with the electrode 68 or the electrode 72, the current flowing through the electric circuit (see FIG. 4) including these electrodes 66 to 72 flows through the electrode 72 to the lead wire 82 without passing through the resistor 80. As a result, the current value of the current flowing through the circuit increases. When the increase in the current value is detected by the current detecting element 84, the slide driver 38 and the closer driver 56 are operated by the computer 36, and the slide motor 39 and the closer motor 59 are driven in reverse. Thus, the door panel 14 moves in the opening direction again (that is, toward the rear side of the vehicle 12), so that the door panel 14 is prevented from being caught by the obstacle.

In the pressure detecting device 10, since the lead wires 82 are connected to the longitudinal ends of the electrodes 66 and 72, the electrodes 66 and 72 except for the longitudinal ends of the electrodes 66 and 72 are connected. (In other words, no dead zone is formed at the longitudinally intermediate portion of the electrode 66 and the electrode 72 such that they do not contact each other even when a pressing reaction force acts). For this reason,
It is possible to reliably detect that the pressing reaction force from the obstacle acts on the front end of the door panel 14.

The lead wires 82 connected to the electrodes 66 and the electrodes 72 near one longitudinal end of the electrodes 66 and the electrodes 72, that is, near the lower end of the front end of the door panel 14, are connected to the vertical direction of the door panel 14. It is extended almost to the center. Here, the lead wire 82 is folded back on the side of the longitudinal end of the outer skin portion 62, is housed in a housing portion 124 formed on the mounting leg 96, and is guided to a substantially central portion in the vertical direction of the door panel 14. From the notch 126 to the notch 13
4 and into the door panel 14 through the holes 130 and 128. In addition, the portion of the lead wire 82 that is folded on the side of the longitudinal end of the outer sheath 62 is the cover 132.
The lead wire 82 is basically not exposed to the outside because it is covered by the wire. Therefore, the appearance near the front end of the door panel 14 is improved, and the foreign matter including the obstacle and the body of the occupant of the vehicle 12 do not directly contact the lead wire 82. Problems such as disconnection due to the body being in contact with the lead wire 82 and pulling the lead wire 82 can be reliably prevented.

Further, in the pressure detecting device 10, the lead wire 82 accommodated in the accommodating portion 124 of the mounting leg 96 is drawn out from the notch 126 and guided to the inside of the door panel 14. Therefore, even if a hole 128 that connects the inside and outside of the door panel 14 is formed at any position in the vertical direction of the front end of the door panel 14, the mounting leg 96 is appropriately cut out according to the position of the hole 128 to cut out. By simply forming the portion 126, the lead wire 82 can be pulled out from the cutout portion 126 and guided into the door panel 14.
Therefore, the pressure sensor 60 can be installed at the front end of the door panel 14 even if the position of the hole 128 is different (that is, the pressure sensor 10 can be attached).

Further, in the pressure detecting device 10, since the accommodating portion 124 is formed in the mounting leg 96 for mounting the pressure-sensitive sensor 60 to the front end of the door panel 14, the protector 90 can be downsized (thinned).

Further, the synthetic resin material forming the protector 90 of the pressure detecting device 10 can be basically one kind, so that the protector 90 can be easily manufactured and the manufacturing cost of the pressure detecting device 10 can be reduced.

The protrusion 158 is described in FIG.
As shown in FIG. 10, it may be specially formed to have a trapezoidal cross section or a triangular cross section.
As shown in FIG.
When the synthetic resin material for forming the lead is attached,
Only around the periphery of 2 becomes wider than the other parts. This wide portion may be used as the protruding portion 158.

The end of the lead wire 82 buried in the mounting leg 158 (that is, housed in the housing portion 156) is connected to the longitudinal direction of the protector 152 in the same manner as in the first embodiment. It is drawn out from the end in the longitudinal direction and connected to the electrodes 66 and 72. Here, as a method of pulling out the lead wire 82 from the protector 152, in the above-described method of forming the mounting legs 154 while fixing the periphery of the lead wire 82 with a synthetic resin material, A method of extending a portion to an appropriate position near the middle portion in the direction without solidifying with a synthetic resin material forming the mounting leg 154, or a method of extending from the longitudinal end of the lead wire 82 embedded in the mounting leg 154 to the middle in the longitudinal direction. A method of cutting the protector 152 along a direction substantially perpendicular to the longitudinal direction while leaving a portion up to an appropriate position near the part, and the like,
Other methods may be used.

Further, as shown in FIG. 9, a notch 126 is formed in the middle of the protector 152 in the longitudinal direction. The notch 126 is basically the same as the notch 126 formed in the mounting leg 96 in the first embodiment, and the other end of the lead wire 82 in the longitudinal direction is drawn out from the notch 126. However, as shown in FIG. 9, the lead wire 82 is cut at the notch 126, and the other end in the longitudinal direction of the lead wire 82 is cut through the notch 126 via the notch 126. The recessed portion 12 is left buried at the other end in the longitudinal direction of the housing portion 156,
The end of the lead wire 82 on the side drawn out from 6 is connected to another lead wire (not shown) and indirectly connected to a power supply.

As described above, in the pressure detecting device 150, the configuration of the housing 156 is basically the same as that of the first embodiment except that the mode of the housing 156 is different from that of the housing 124 in the first embodiment. Configuration. Therefore, the first
The same operation as the pressure detecting device 10 according to the embodiment is exerted, and the same effect as the pressure detecting device 10 can be obtained.

Further, in the present pressure detecting device 150, as described above, the protector 1 together with the holding portion 92 and the flexible portion 94 are provided.
The lead wire 82 can be embedded in the mounting leg 154 by arranging the lead wire 82 at a position where the mounting leg 154 is formed when forming the mounting wire 52 and solidifying the periphery of the lead wire 82 with a synthetic resin material (that is, the lead). The wire 82 can be housed in the housing 156). Therefore, if the protector 152 is formed to be sufficiently longer than the length of the front end of the door panel 14 in the vertical direction, the protector 152 may be appropriately cut and used according to the length of the front end of the door panel 14 in the vertical direction. Even if the length of the front end of the door panel 14 in the vertical direction is different for each vehicle type, it can be easily coped with, and the cost can be reduced.
