Description

  The present invention relates to a door opening and closing device that opens and closes a sliding door provided on a side portion of a vehicle body.

  Many wagon-type and one-box type vehicles have a sliding door on the side of the vehicle body. The slide door is guided by a guide rail provided along the side surface of the vehicle, and the entrance / exit is opened and closed by the operator pushing and pulling the slide door. However, sliding doors are often applied to relatively large entrances and exits, and the sliding doors themselves tend to be larger, so opening and closing operations are particularly difficult on slopes where the weight of the sliding doors acts in the opening and closing direction. There was a problem that became difficult.

  Therefore, an opening / closing device has been developed in which a driving force such as an electric motor is used for opening / closing the sliding door in order to easily open / close the sliding door (for example, see Patent Document 1). The opening / closing device includes a helical shaft driven by an electric motor as a driving mechanism, and a sliding member fixed to the sliding door is engaged with the helical shaft. When opening and closing the sliding door, the rotational motion of the electric motor is converted into the opening and closing motion of the sliding door via the spiral shaft and the sliding member.

  In such an opening / closing device, the drive mechanism is attached to the space between the side sill and the step panel. As a method for attaching the drive mechanism in this case, the step panel with the drive mechanism assembled in advance is fixed on the side sill, or the drive mechanism is attached from the gap between the step panel fixed to the vehicle and the side sill. Yes.

In addition, as a sliding door opening and closing device, an opening and closing device has been developed that uses a cable to pull the sliding door in the opening and closing direction. The opening / closing device includes a roller assembly that is connected to the slide door and guided by the guide rail, and a drive unit that pulls out and pulls the cable connected to the roller assembly. The cable is wound up by the drive unit. In such a cable type switchgear, the drive unit is often attached to the side panel of the rear fender portion.
Japanese Patent No. 2840365 (page 2-3, Fig. 1-2)

  However, when fixing a step panel with a drive mechanism mounted on the side sill in advance, the step panel that covers the lower surface of the entrance and supports the weight of the passenger is a member that requires strength and has a considerable size and weight. Therefore, if a drive mechanism is attached to the step panel in advance, it is conceivable that the weight of the step panel increases and the workability of mounting on the vehicle deteriorates. Also, when assembling the drive mechanism between the side sill and the step panel from the gap that opens to the side of the vehicle, if the priority is given to aesthetics, the width of the gap becomes narrower and the workability is worsened. There was a problem.

  On the other hand, if the drive unit is to be mounted on the side panel, when assembling the vehicle, the worker enters the vehicle interior, installs the drive unit inside the side panel, and then goes out of the vehicle compartment to connect the roller assembly and cable. There is a problem in that not only is the load imposed on the operator, but the number of work steps is increased.

  In addition, various devices such as electronic devices, blowers, and speakers are mounted on the side panel, and mounting the drive unit on this side panel places significant restrictions on the dimensions and mounting position of the drive unit. It will also increase the cost.

  Furthermore, mounting the drive unit on the side panel also brings the drive unit closer to the ears of the occupant riding in the rear seat, which is not preferable from the viewpoint of noise. In addition, since the side panel is a low-rigid thin plate having a large number of openings, there is also a possibility that the drive unit may generate vibration.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a door opening and closing device that improves workability when attaching to a vehicle body and improves vehicle quality.

  The door opening and closing device of the present invention is a door opening and closing device that opens and closes a sliding door provided at the entrance of a vehicle body, and is provided below a floor panel that forms a passenger compartment floor and is connected to the sliding door.

  The door opening and closing apparatus of the present invention is characterized in that at least one of the first attachment port and the second attachment port is formed near the lower part of the seat.

  According to the present invention, the floor panel is formed with the first attachment opening that opens near one end of the guide rail, the rotating body is attached to the first attachment opening, and the second opening that opens near the other end of the guide rail to the floor panel. Since the attachment opening is formed and the reversing roller is attached to the second attachment opening, the assembling work of the door opening / closing device can be simplified. That is, since the door opening and closing device can be assembled without the operator going back and forth between the vehicle interior and the exterior of the vehicle interior, the assembly can be easily performed and the number of work steps can be reduced. Further, the present invention is not limited to the assembly of the door opening / closing device, and the work cost can be reduced because the operation can be easily performed even when the door opening / closing device is inspected or repaired.

  Moreover, since the rotating body and the reverse roller are attached to the floor panel, it is possible to reduce in-vehicle noise when opening and closing the sliding door. That is, by attaching the door opening / closing device to the floor panel, the door opening / closing device can be moved away from the passenger's ear, and the operation sound can be blocked by the floor panel, so that the vehicle quality can be improved. Furthermore, it is not necessary to adjust the layout with other in-vehicle devices mounted on the side panel, and the design cost can be reduced. Furthermore, since the floor panel is higher in rigidity than the side panel, the vibration of the door opening and closing device can be suppressed, and the vehicle quality can be improved.

  Furthermore, by accommodating the door opening / closing device in the boarding / alighting step, the door opening / closing device can be housed with good appearance, and the vehicle quality can be improved. Moreover, the soundproofing effect can be enhanced by the step panel.

  Furthermore, since at least one of the first mounting port and the second mounting port is formed in the vicinity of the lower part of the seat, the vehicle quality can be improved in terms of soundproofing and appearance.
