Description

  The present invention provides a side cover structure that covers the gap between the door and the outer wall of the vehicle body from a side view when the sliding door that opens and closes the entrance / exit of the vehicle reaches a fully open position. The present invention relates to a cover structure for a sliding door that is supported on a vertically peripheral edge so as to be swingable.

A slide door is known as a door that opens and closes an entrance / exit provided on a side wall of a vehicle.
As this sliding door, slide rails are provided at the upper and lower parts of the entrance and exit, the base ends of the slide arms are attached to the upper and lower sides of the door, the sliding ends of each slide arm are fitted to the slide rails via rollers, A three-point support type sliding door is used in which the center of the rear end of the door is slidably supported by a third rail attached to the center of the rear side of the vehicle body outer wall.

  On the other hand, a slide rail is provided at the center in the vertical direction of the slide door, and the slider and the vehicle body side base frame that are slidably fitted to the slide rail are connected by a parallel link, whereby the door is located at the same position as the closed position. 2. Description of the Related Art A swing slide door is known that slides between a projecting position that is swung outward and a fully open position at the rear or front of a vehicle body from the projecting position. An example of a swing slide door including a swing slide unit that is a door opening and closing device is disclosed in Patent Document 1 and Patent Document 2.

  In such a three-point support type sliding door or swing sliding door, when the door is fully opened, a gap with a predetermined width is formed in the vehicle width direction region between the door and the side wall of the vehicle body. The aesthetics are reduced from the point of being open. Particularly, a swing sliding door employs a door opening / closing device in which a slider slidably fitted to a slide rail and a vehicle body side base frame are connected by a parallel link, and a predetermined opening / closing drive mechanism is attached thereto. This door opening and closing device is arranged so that the vehicle body side frame and the parallel link connected thereto can be displaced in the gap between the door and the side wall of the vehicle body. There is a possibility that a foreign object or a passenger's hand enters the vehicle, and it is necessary to prevent this.

  Thus, for example, in the swing slide door opening / closing device disclosed in Japanese Patent Application No. 2007-256358 previously proposed by the present applicant, the door Dr is closed as shown in FIGS. 10 (a) and 10 (b). When the fully open position D3 is reached from the position D1, the arm cover C1 and the link cover C2 work together to swing the gap e1 between the door Dr and the vehicle body outer wall Sp and the main part of the door opening / closing device provided there. It is configured to cover the slide unit U. Here, the arm cover C1 is pivotally supported by the vehicle body side mounting frame D, and the link cover C2 is pivotally supported by the door side inner wall. In this case, when the door Dr reaches the fully open position D3 shown in FIG. 10B from the closed position D1 in FIG. 10A, the arm cover C1 has a gap E between the door and the vehicle body outer wall from the overlapping position q1 overlapping the door. The swing slide unit U is rotated and biased by the elastic force of a spring (not shown) at a covering position q2 that covers the front slide Frn.

  Here, the pivot end portion of the arm cover C1 is pivotally supported by the vehicle body side mounting frame D coupled to the quarter panel SP in the vicinity of the longitudinal peripheral portion of the door opening. Further, the quarter inner panel SP forming the inner wall of the vehicle is covered from the vehicle inner side by the quarter trim QT.

JP 2003-320964 A Japanese Patent Laid-Open No. 10-175444

  By the way, even when the arm cover C1 is held at the covering position q2 that covers the gap E and the swing slide unit U from the front (see FIG. 10B), the pivot end of the arm cover C1 and the quarter trim A gap t1 is formed between the tips of the QTs, and the aesthetics deteriorate in front view. In order to prevent this, the cloth-like cover B1 is connected to the pivot end portion of the arm cover C1, and the base end side of the cloth-like cover B1 is wound around the retractor RT. The retractor RT is accommodated in the in-wall space e1 of the quarter trim QT. In this case, the cloth-like cover B1 can be retracted from the front end of the quarter trim QT and reaches the pivot end of the arm cover C1, thereby closing the gap t1.

  However, when such a structure is adopted, the amount of expansion of the quarter trim QT into the vehicle interior increases, the number of parts increases, and a sufficient mounting system is required to prevent malfunction, resulting in an increase in cost. In addition, the cloth-like cover B1 and the arm cover C1 can cover the gap E and the swing slide unit U on the rear side thereof, but this cannot be regulated against visual inspection from the top or intrusion of passengers' hands or objects. The sense of harm cannot be reduced reliably.

Is wound around the winding drum 46. As a result, the rear door 4 is swung and displaced from the closed position D1 to the protruding position D2 shown in FIGS. At this time, the front arm 31 swings around the front arm swing base point pcf, and the front roller Prf at the swing end of the front arm 31 is kept in contact with the stopper wall rs of the lower main downward rail groove 33l. Furthermore, since the previous roller Prfs in the vicinity of the front roller Prf keeps the roller contact state outside the stopper wall rs, the center line of the front roller 23f is prevented from shifting in the front-rear direction X, and the parallel link is reliably shaken. As shown in FIGS. 7 (b) and 8 (b), the rear door 4 protrudes and holds the position D2. At the same time, the side cover 75 swings in the vehicle outward direction, and the state in which the swing end of the arm cover 91 abuts on this is maintained. Even in this operating range, these covers 75 and 91 maintain an aesthetic appearance.

Furthermore, the swinging of the parallel link 16 stops after the protruding position D2, and the door support rail 22 side is moved to the fully open position D3 shown in FIG. 7C relative to the slider 24 at the swinging end of the parallel link 16. Operate sliding. In this state, as shown in FIG. 7C, the gap E between the rear door 4 and the outer surface of the vehicle body is enlarged, and at the same time, the link on the swing slide unit U side protrudes relatively large toward the outside of the vehicle.
In this state, as shown in FIG. 8C, the arm cover 91 abuts against the load support arm 18, swings the swing end forward, and the front side of the swing end is covered with the side cover 75. At this time, since the side cover 75 is elastically urged to rotate in the direction of the fully open position D3 around the vertical center line Lh, the swing end 755 comes into contact with or approaches the door trim 80.

Even in the fully open position D3, the side cover 75 that fits the base end portion to the quarter trim 74 cooperates with the upper cover portion 754, that is, the side cover 75 is in front of the gap E and the swing slide unit U. The upper cover part 754 can cover the upper part, respectively, to prevent foreign matters or passengers from entering the swing slide unit U and to ensure the safety of the passenger's hand and to block the eyes from the passenger compartment and the front of the passenger compartment. be able to.
Further, in this state, the side cover 75 at the covering position K2 covers the casing facing surface fc of the longitudinal axis portion 752 with the tip edge k of the arc-shaped cover portion 741c of the quarter trim 74. In addition, the upper cover portion 741a of the quarter trim 74 also covers the upper side surface fs (upper side of the vertical axis portion) of the upper pivot support portion 761 and a part of the upper cover portion 754. In this case, as shown in FIG. 5 (b), the gap tj between the tip edge k of the arc-shaped cover part 741c and the casing facing surface fc of the vertical axis part 752, or the upper cover part 741a and the upper pivot part 761. The upper side surface fs (upper side of the vertical axis portion) is reliably covered, and the closed state can be maintained while maintaining a beautiful appearance with no sense of incongruity when viewed from the passenger compartment and the front of the passenger compartment.

Next, it is assumed that the door opening / closing switch (door opening / closing operation means) SW1 provided in the rear door 4 is pressed again and the controller 30 receives a door closing command.
In this case, the motor M of the door-side drive mechanism 19 is driven to operate reversely to the states of FIGS. 7B and 7A, and the side cover 75 and the arm cover 91 are respectively oscillated in reverse to the opening operation. Move.
Further, when the rear door 4 reaches the half latch position immediately before the closing position D1, the opening / closing control unit 301 stops the motor M of the door side drive mechanism 19. Next, the latch drive control unit 302 drives a motor (not shown) of the latch drive means 191 to fully latch the front end upper lock portion J1, the front end lower lock portion J2, and the rear end lock portion J3 of the rear door 4, and close the rear door 4. Hold at position D1.

As a result, the rear door 4 holds the closed position D1, the side cover 75 is held at the overlapping position K1, and the side cover 75 and the arm cover 91 overlap the door trim 80 without a sense of incongruity, and these do not narrow the vehicle compartment width. , Ensuring aesthetics.
