Description

  The present invention relates to a slide door device used in an automobile.

  The sliding door type automobile is configured to open and close by sliding the door body in the front-rear direction with respect to the vehicle body opening. For example, a slide door device in which a rail is formed on the vehicle body surface behind the vehicle body opening, a roller is disposed on the vehicle interior side panel of the door body, and the roller rolls in the rail has been put into practical use. . However, this type of sliding door device has a problem in that it looks bad because the rail appears on the surface of the vehicle.

  Therefore, in recent years, for example, in Japanese Patent Application Laid-Open No. 2002-137634, a rail extending in the vehicle front-rear direction is disposed at the center in the vertical direction of the door body, and a guide roller provided at the rear edge of the vehicle body opening is placed on the rail. A sliding door device configured to roll has been proposed. According to such a sliding door device, since rails and rollers do not appear on the surface of the vehicle, it looks good.

  However, in such a sliding door device, it is necessary to devise a method for supporting the load of the door body when the door body is fully opened. Therefore, in the technique described in the above publication, a support roller is provided at the rear end of the rear fender of the outer plate of the vehicle body so as to advance outward when the door body is fully opened and engage with the rail. The front and rear parts of the main body are supported. However, according to this technique, the appearance of the rear fender is deteriorated because the arrangement portion of the support roller is visually recognized when the door body is closed.

  Therefore, in JP 2008-133710 A, an arm that pushes the door body outward in the vehicle width direction at the initial opening of the door body is disposed so as to protrude from the rear edge of the vehicle body opening, and is engaged with the rail. There has been proposed a sliding door device having a cart that holds a door body on its arm. According to this technique, since the door body can be supported by the cart and the arm, the above-described support roller or the like is not required and the appearance quality is improved.

  However, in this sliding door device, when the door body is pushed outward in the vehicle width direction by the arm, the engagement between the cart and the rail is fixed and the load from the door body is supported. A joint portion and an arm side engaging portion that engages with the vehicle body side engaging portion are formed. Therefore, there is a problem that the structure becomes complicated. Further, in order to securely engage the vehicle body side engaging portion and the arm side engaging portion, it is necessary to manufacture with high dimensional accuracy, and the cost increases accordingly.

JP 2002-137634 A JP 2008-133710 A

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a slide door device that can support the load of the door body with a simple structure and that does not impair the appearance of the automobile.

The features of the sliding door device of the present invention that solves the above-mentioned problems are a door body that is disposed in a vehicle body opening and that opens and closes the vehicle body opening by sliding in the vehicle front-rear direction, and a door body that extends along the vehicle front-rear direction. A door rail disposed in a recess formed in the vehicle interior side panel, an arm rotatably held by the vehicle body frame, and an upper side and a lower side parallel to each other held by the arm so as to be rotatable in the vehicle width direction. A support member disposed at the end of the vehicle body opening on the door opening direction side, a central roller group that is rotatably supported by the support member, and a rocker portion of the vehicle body that extends along the vehicle front-rear direction. A rocker rail and a rocker roller group provided at an end opposite to the end facing the support member of the door body and guided by the rocker rail,
The central roller group includes a pair of front and rear upper vertical rollers disposed in the vehicle front-rear direction near the upper side of the support member, and a front and rear disposed in the vehicle front-rear direction near the upper side of the support member. A pair of upper horizontal rollers, a pair of front and rear lower vertical rollers disposed near the lower side of the support member in the vehicle longitudinal direction, and a space between the lower sides of the support member and spaced apart from each other in the vehicle longitudinal direction. A pair of front and rear lower and horizontal rollers,
The door rails are spaced apart from each other in the vertical direction, the upper rail has a guide surface on the upper surface, the lower rail has a guide surface on the lower surface, and the vehicle interior side panel is fixed to the vehicle interior side panel at a distance from each other in the vehicle interior side. A pair of upper and lower horizontal rails having a guide surface facing the bottom wall surface of the recess of the panel,
The pair of front and rear upper vertical rollers roll between the guide surface of the upper rail and the upper wall surface of the recess, and the pair of front and rear lower vertical rollers roll between the guide surface of the lower rail and the lower wall surface of the recess. The pair of front and rear upper horizontal rollers and the pair of front and rear lower horizontal rollers roll between the guide surface of the horizontal rail and the bottom wall surface of the recess, and the support member is slidably engaged with the door rail via the central roller group. There is in being.

  According to the slide door device of the present invention, the support member is slidably engaged with the door rail via the central roller group, and when the door body is opened and closed, the central roller group moves in the vertical direction and the vehicle width direction with respect to the door rail. Rolls in a reliably regulated state.

  That is, a pair of upper vertical rollers spaced apart in the front-rear direction of the vehicle is disposed on the upper portion of the support member, and a pair of lower vertical rollers spaced apart in the front-rear direction of the vehicle are disposed on the lower portion, Since each of them is supported by the upper rail, the lower rail, and the side wall surface of the recess, the load in the vertical direction of the door body can be reliably supported at four locations, up, down, left, and right. In addition, a pair of upper horizontal rollers spaced apart in the longitudinal direction of the vehicle is disposed on the upper portion of the support member, and a pair of lower lateral rollers spaced apart in the longitudinal direction of the vehicle are disposed on the lower portion, each of which is spaced apart in the vertical direction. Is supported by the pair of horizontal rails and the bottom wall surface of the recess, so that the load in the vehicle width direction of the door body can be reliably supported at four locations, top, bottom, left and right.

  Further, a rocker roller group provided at the end of the door body opposite to the support member is guided by the rocker rail.

  Therefore, according to the sliding door device of the present invention, since a stable opening / closing operation is ensured without using the vehicle body side engaging portion and the arm side engaging portion as described in Patent Document 2, high dimensional accuracy becomes unnecessary. Cost can be reduced.

  The slide door device described in Patent Document 2 requires an upper guide mechanism. However, according to the present invention, the upper guide mechanism can be made unnecessary, so that the appearance is improved. Further, since the guide rail of the upper guide mechanism is often an arc-shaped curved surface due to the design of the vehicle, the structure of the upper guide mechanism is complicated. However, in the present invention, since the upper guide mechanism is not required, the structure becomes simple, and the cost can be reduced and the weight can be reduced.

  The rocker rail as the lower guide mechanism includes an upper guide surface and a lower guide surface extending in parallel with each other along the vehicle longitudinal direction, an outer guide surface extending in parallel with each other along the vehicle longitudinal direction and spaced apart from each other in the vehicle width direction. The rocker roller group has a vertical rocker roller and a horizontal rocker roller, the vertical rocker roller rolls between the upper guide surface and the lower guide surface, and the horizontal rocker roller is the outer guide. By rolling between the surface and the inner guide surface, the rocker roller group rolls in a state where movement in the vertical direction and the vehicle width direction is restricted with respect to the rocker rail. Therefore, the opening / closing operation is further stabilized.

Since each is supported by the upper rail, the lower rail, and the side wall surface of the recess, the load in the vertical direction of the door main body can be reliably supported at four locations, up, down, left and right.

  In addition, a pair of upper horizontal rollers spaced apart in the longitudinal direction of the vehicle is disposed on the upper portion of the support member, and a pair of lower lateral rollers spaced apart in the longitudinal direction of the vehicle are disposed on the lower portion, each of which is spaced apart in the vertical direction. Is supported by the pair of horizontal rails and the bottom wall surface of the recess, so that the load in the vehicle width direction of the door body can be reliably supported at four locations, top, bottom, left and right.

  That is, the support member is reliably engaged and held by the door rail, and the load in the vertical direction and the vehicle width direction of the door body can be reliably supported by the four corners of the support member, so that stable sliding movement is possible. And the magnitude | size of the load which can be supported can be adjusted by adjusting the space | interval of the rollers of a center roller group, ie, the distance of the four corners of a supporting member.

  The sliding door device of the present invention includes a rocker rail and a rocker roller group in addition to the above-described configuration. The rocker rail is provided in the rocker portion of the vehicle body and extends along the vehicle front-rear direction. The rocker roller group is provided at an end opposite to the end facing the support member of the door body, and is guided while rolling in the rocker rail. Therefore, one end of the door body can be reliably guided by the engagement between the rocker rail and the rocker roller group.

  The rocker rail has an upper guide surface and a lower guide surface that extend in parallel with each other along the vehicle longitudinal direction, and an outer guide surface and an inner guide surface that extend in parallel with each other along the vehicle longitudinal direction with a space therebetween in the vehicle width direction. The rocker roller group includes a vertical rocker roller and a horizontal rocker roller, the vertical rocker roller rolls between the upper guide surface and the lower guide surface, and the horizontal rocker roller is formed between the outer guide surface and the inner guide surface. It is desirable to roll between. With this configuration, the rocker roller group rolls in a state where movement in the vertical direction and the vehicle width direction is restricted with respect to the rocker rail, so that the opening and closing operation of the door body is further stabilized.

  In addition, it is desirable that at least one of the vertical rocker roller and the horizontal rocker roller is provided in a pair along the vehicle front-rear direction at a distance.
