JP 2007-56522 A Japanese Patent Laid-Open No. 11-182136

  The techniques described in Patent Document 1 and Patent Document 2 described above detect foreign object pinching, and do not prevent foreign object pinching itself.

  The present invention has been made in view of the above circumstances, and its purpose is to provide a space between the sliding door and the rear edge of the side opening when the sliding door is displaced from the closed position to the open position. It is an object of the present invention to provide a sliding door pinching prevention structure that can prevent a foreign matter from being caught in a gap formed in the sliding door.

In order to achieve the above object, the following solution is adopted in the present invention. That is, as described in claim 1 in the claims,
A closed position covering the side opening formed on the side surface of the vehicle body, and the side opening by being moved rearward along the outer side surface of the rear vehicle body once displaced outward from the closed position in the vehicle width direction. An open position, a sliding door adapted to be able to take,
Drive means for driving the sliding door between the closed position and the open position;
Drive control means for controlling the drive of the drive means;
An intrusion detection sensor that is arranged to extend in the vertical direction with respect to the rear edge of the side opening, and that is activated when an object comes into contact with the front,
With
The rear edge portion of the side opening is configured by joining the two flange portions together as a joint flange portion extending forward at each front end portion of the outer panel and the inner panel constituting the vehicle body,
The intrusion detection sensor is disposed in front of the joint flange portion,
The drive control means is configured such that when a foreign object is detected by the intrusion detection sensor while the sliding means is driving the sliding door in the closed position toward the open position, the sliding by the driving means is performed. Set to control the door to stop driving,
It is like that. According to the above solution, when a foreign object tries to enter the gap from the vehicle interior side, the foreign object contacts (presses) the intrusion detection sensor from the front, and the intrusion detection sensor is activated. . Due to the operation of the intrusion detection sensor, the drive toward the open position of the slide door is stopped, and a situation in which foreign matter is caught in the gap is prevented in advance.

Further, the joining flange portions formed at the front end portions of the outer panel and the inner panel constituting the rear edge portion of the side opening are joined to each other, and the intrusion detection sensor is forward of the joining flange portion. It is possible to place the intrusion detection sensor at the front position as much as possible in the rear edge of the side opening, and foreign matter from the inside of the vehicle cabin tries to enter the gap. This is preferable for early and reliable detection.

A preferred mode based on the above solution is as described in claim 2 and the following claims. That is,
A seal member extending in the vertical direction is attached to the joint flange portion,

(Corresponding to claim 2 ). In this case, the intrusion detection sensor can be incorporated by effectively using the seal member attached to the joint flange portion. In addition, the intrusion detection sensor is a soft member and is incorporated in a seal member that can be easily elastically deformed. Therefore, the intrusion detection sensor is preferable in reducing the impact when it comes into contact with the intrusion detection sensor.

The intrusion detection sensor is formed between an inner side surface in the vehicle width direction of the slide door and a rear edge portion of the side opening when the slide door is displaced from the closed position toward the open position. It arrange | positions so that it may face the clearance gap made (corresponding to claim 3 ). In this case, it is preferable for reliably detecting the intrusion of foreign matter in the sandwiched direction.

An armrest protrudes from the inner side surface in the vehicle width direction of the sliding door,
The intrusion detection sensor extends in a vertical direction from a position higher than the upper surface of the armrest to a lower position,
(Corresponding to claim 4 ). In this case, it is possible to reliably detect a situation where an object as a foreign object placed on the armrest attempts to enter the gap.

On the inner side surface in the vehicle width direction of the slide door, a pedestal portion to which an open / close switch or an inner door handle for instructing opening / closing of the slide door is attached is projected and formed.
The intrusion detection sensor extends in a vertical direction from a position higher than the upper surface of the pedestal portion to a lower position,
(Corresponding to claim 5 ). In this case, it is possible to reliably detect a situation where an object as a foreign object that is often located on the pedestal portion tries to enter the gap.

On the inner side surface in the vehicle width direction of the sliding door, a storage box for storing small items such as plastic bottles is formed protrudingly,
The intrusion detection sensor extends vertically from a position higher than the upper surface of the storage box to a lower position,
(Corresponding to claim 6 ). In this case, it is possible to reliably detect a situation where a foreign object as an object often placed on the storage box attempts to enter the gap.

The rear edge portion of the side opening has a rear edge front surface portion extending in the vertical direction and facing forward, and a rear edge side surface portion extending forward from the vehicle width direction inner side end of the rear edge front surface portion. The rear edge front surface portion and the rear edge side surface portion constitute a wet edge portion that is concave toward the vehicle body inward side,
The front end portion of the side rear edge portion is formed by a joining flange portion that is formed at each front end portion of the outer panel and the inner panel constituting the rear edge portion of the side opening portion and joined to each other.

(Corresponding to claim 7 ). In this case, a specific structure at the rear edge of the side opening is provided, and an effect similar to the effect corresponding to claim 2 can be obtained.

  According to the present invention, when the slide door is displaced from the closed position to the open position, it is possible to prevent a foreign matter from being caught in the gap formed between the slide door and the rear edge of the side opening. it can.

  1 to 4, reference numeral 1 denotes a vehicle body, the B pillar (center pillar) of which is indicated by reference numeral 2, the C pillar located immediately after the B pillar 2 is indicated by reference numeral 3, and the C pillar 3 The last D-pillar located immediately after is indicated by reference numeral 4.

  As can be understood from FIG. 3 in particular, a side opening 10 is opened between the B pillar 2 and the C pillar 3 on the side surface of the vehicle body. This side opening 10 is used for passengers getting on and off using the rear seats (second row of seats) 11, the front edge portion thereof is constituted by the B pillar 2, and the rear edge portion C pillar 3. The lower edge portion is constituted by a side sill 12, and the upper edge portion is constituted by a roof side rail (the outer end portion in the vehicle width direction of the roof panel) 13.

  The side opening 10 is opened and closed by a slide door 20. That is, the slide door 20 can take a closed position (the state shown in FIG. 1) that covers (closes) the side opening 10 and an open position that opens the side opening 10. More specifically, the slide door 20 is displaced from the closed position in FIG. 1 to the outer side in the vehicle width direction and then moved rearward along the rear fender 14 so that the side opening 10 is almost completely opened. Open position (movement indicated by an arrow in FIG. 1). FIG. 2 shows a state in which the slide door 20 is once displaced outward from the closed position and slightly rearward. Of course, the return of the slide door 20 from the open position to the closed position is the reverse of the movement from the closed position to the open position. As will be described later, the slide door 20 is an electric type that is opened and closed by a motor.

  As shown in FIG. 3, the C pillar 3 constituting the rear edge portion of the side opening 10 includes a rear edge front surface portion 3 a and a rear edge side extending forward from the vehicle width direction inner side edge of the rear edge front surface portion 3 a. And a surface portion 3b. The outer end in the vehicle width direction of the rear edge front surface portion 3 a is continuous with the front end of the rear fender 13. In this way, the rear edge of the side opening 10 is a wet edge that is slightly recessed inward in the vehicle width direction from the rear fender 14 constituting the vehicle body outer surface by the rear edge front surface portion 3a and the rear edge side surface portion 3b. Part 15 is configured. The wet edge corresponding to the wet edge 15 is also formed in each part of the B pillar 2, the side sill 12, and the roof side rail 13.

  The slide door 20 in the closed position is housed in the wet edge 15 so that the outer surface of the slide door 20 is flush with the rear fender 14. In other words, the degree of depression (dimension in the vehicle width direction) of the wet edge 15 (of the rear edge front surface portion 3a) inward in the vehicle width direction depends on the thickness of the slide door 20 in the vehicle width direction. Will be set. Moreover, the dimension in the front-rear direction of the rear edge side surface portion 3b is set to a dimension that allows draining (edge cutting) between the interior and exterior of the vehicle interior.

On the inner side surface in the vehicle width direction of the slide door 20, an armrest 21, a storage box 22 for storing small items such as plastic bottles at a position in front of the armrest 21, and a pedestal portion 23 are formed to protrude. As shown in FIGS. 4 and 5, the armrest 21 has an upper surface height position slightly higher than the seat surface of the seat cushion 11 </ b> A of the rear seat 11 (substantially intermediate position in the vertical direction of the seat back 11 </ b> B). Is set to Further, the height position of the upper surface of the storage box 22 is set to a height position substantially the same as the seat surface of the seat cushion 11A. Further, the pedestal portion 23 is set so that the upper surface thereof is substantially the same height as the upper surface of the armrest 21, and an open / close switch 72 is attached to the upper surface of the pedestal portion 23, and upward from the upper surface of the pedestal portion 24. An inner door handle 24 is arranged. The opening / closing switch 72 commands opening / closing of the slide door 20 as will be described later. The inner door handle 24 gives a force for opening and closing the slide door 20. The inner door handle 24 is provided with an inner door switch for instructing opening and closing of the slide door 20, as will be described later. ing.

  Due to the displacement of the slide door 20 from the closed position toward the open position, there is a gap between the inner side surface in the vehicle width direction of the slide door 20 and the C pillar 3 (the outer end in the vehicle width direction). S is formed (see FIGS. 2 and 4). In order to prevent foreign matter from entering the gap S from entering the gap S, an intrusion detection sensor 25 is provided at the front end portion of the rear edge side surface portion 3b which is a part of the rear edge portion of the side opening 10. Is installed. The intrusion detection sensor 25 extends in the vertical direction, and its upper end position is set near the height of the belt line of the slide door 20 (near the upper end portion of the seat back 11B in the standing position), and its lower end position is The side sill 12 is located in the immediate vicinity.

  The intrusion detection sensor 25 extending in the up-down direction, as can be understood from FIG. It extends from a position higher than the position to a position lower than the position (the respective upper surfaces are positioned within the length range of the intrusion detection sensor 25 in the vertical direction). Thereby, for example, when the slide door 20 is displaced from the closed position toward the open position in a state where an occupant places his arm on the armrest 21, the arm as an object (foreign matter) is moved against the intrusion detection sensor 25. Then, the intrusion detection sensor 25 is actuated by abutting from the front. When the intrusion detection sensor 25 is actuated, as will be described later, the drive toward the open position of the slide door 25 is forcibly stopped, and foreign matter can be prevented from entering the gap S. Will be. Note that after the drive of the slide door 20 is stopped, the slide door 20 may be slightly reversed toward the closed position.

  FIG. 6 shows a specific example of incorporating the intrusion detection sensor 25 into the vehicle body. In FIG. 6, the outer panel of the slide door 20 is indicated by reference numeral 20A, the inner panel is indicated by reference numeral 20B, and the trim material is indicated by reference numeral 20C. Further, for the C pillar 3, the outer panel is indicated by reference numeral 3A, the inner panel is indicated by reference numeral 3B, and the reinforcement is indicated by reference numeral 3C. In addition, 5 in FIG. 6 is the trunk side trim material which covers the inner panel 3B from the vehicle interior side.

  The C pillar 3 constituting the rear edge of the side opening 10 has a front flange between the outer panel 3A and the inner panel 3B, which is a joint flange 3d or 3e extending forward, and this joint flange 3d. And 3e are joined together. And the sealing member 26 is fitted and integrated from the front with respect to the joining part of this joining flange part 3d and 3e. The seal member 26 is formed of a bullet member and cooperates with a seal member 27 provided on the slide door 20 in the closed position to seal the side opening 10 in a liquid-tight manner.

The seal member 26 is formed in an annular shape so as to surround the entire peripheral edge of the side opening 10. And the intrusion detection sensor 25 mentioned above is incorporated in the front end part in the attachment part to the rear edge part of the side opening part 10 among the said sealing members 26. FIG. That is, the intrusion detection sensor 25 is integrated into the seal member 26 so as to exist only in the range shown in FIGS. 3 and 4 of the seal member 26 (in FIGS. 3 and 4, Only the intrusion detection sensor 25 is highlighted). Such an intrusion detection sensor 25 can be constituted by, for example, a plurality of conductors built in the seal member 26 within a predetermined range. That is, since this conductor is pressed in the front-rear direction and the vehicle width direction (at least the front-rear direction) as the sensitivity direction, it approaches or comes in contact, and the electrical resistance value changes from the non-conductive state to the conductive state. It is possible to detect (determine) whether or not a foreign substance is in contact with the electric resistance value, depending on whether or not the electric resistance value exceeds a predetermined threshold value. The intrusion detection sensor 25 is not limited to the above, and in addition, for example, a piezoelectric element, an optical fiber, or the like whose electrical characteristics and light transmittance are changed by being compressed and deformed is used. An appropriate sensor can be used.

  FIG. 7 shows an example of a drive portion of the slide door 20 that is electrically operated. In FIG. 7, reference numeral 60 denotes a guide rail, and the guide rail 60 is fixed to the vehicle body so as to extend along the rear fender 14 from the wet edge 15. A slider 62 such as a pulley held by a bracket 61 slidably held at the rear end of the slide door 20 is fitted into the guide rail 60 so that it can move smoothly.

  A guide wire 63 is connected to the bracket 61. The guide wire 63 is disposed along the guide rail 60 by a guide pulley 64. The guide wire 63 is reciprocated by the drive mechanism 65. That is, the drive mechanism 65 has a drive pulley (not shown) engaged with the motor 65a, the speed reduction mechanism 65b, and the guide wire 64. The guide wire 63 is driven to reciprocate by driving the drive pulley forward or backward through the speed reduction mechanism 65b by the motor 65a. Of course, the slide door 20 is driven between the closed position and the open position by the reciprocating movement of the guide wire 63.

  FIG. 8 shows a control system of the motor 65a. In the figure, U is a controller (control unit) configured using a microcomputer. In addition to receiving signals from the intrusion detection sensor 25, the controller U also receives signals from various switches 71 to 75. Each of the switches 71 to 75 is manually operated to command opening / closing of the slide door 20. That is, the switch 71 is provided in the driver's seat, the slide door switch 72 is provided on the upper surface of the pedestal portion 23 as described above, and the remote control switch 73 is carried by the passenger. The inner door switch 74 is activated in response to the opening / closing operation of the inner door handle 24 described above. Similarly, the outer door switch 75 is provided on an outer side surface of the slide door 20 in the vehicle width direction, and is provided on an outer door handle (not shown) to which an external force in the opening / closing direction is given by an occupant trying to sit on the rear seat 11. It was attached. Note that the opening / closing switch may have only a part of the above five types.

  When the controller U receives an open command from any one of the switches 71 to 75 in a state where the slide door 20 is in the closed position, the controller U drives the motor 65a toward the open position. Execute the control in the direction to do. If the intrusion detection sensor 25 is turned on while the slide door 20 is being driven from the closed position toward the open position, the drive of the slide door 20 toward the open position is stopped. In addition, after the drive is stopped, the slide door 20 can be controlled to be slightly reversed toward the closed position.

  The control content of the controller U described above is shown in the flowchart of FIG. Hereinafter, this flowchart will be described. In the following description, Q indicates a step. In addition, the flowchart of FIG. 9 is started on the premise that the vehicle speed is 0 (stopped) from the viewpoint of safety. First, at Q1, it is determined whether or not the slide door 20 is currently in the closed position. If the determination in Q1 is YES, it is determined in Q2 whether or not there is an open command signal from at least one of the switches 71 to 75. If the determination in Q2 is YES, the slide door 20 is driven toward the open position in Q3 (drive of the motor 65a). Thereafter, in Q4, it is determined whether or not the intrusion detection sensor 25 is ON. If the determination in Q4 is YES, the drive toward the open position of the slide door 20 is forcibly stopped. Note that, after the drive is stopped, the slide door 20 may be driven to reverse slightly toward the closed position. When NO is determined in Q1, NO is determined in Q2, or NO is determined in Q4, the process returns without passing through Q5 (the drive to the open position of the slide door 20 is allowed). .
