Description

  The present invention relates to a seal structure for a vehicle opening / closing body, and preferably to a vehicle opening / closing body seal structure at a door contact portion between a vehicle body rear opening panel and a resin rear gate inner panel.

In a vehicle such as a hatchback or a wagon type automobile, the rear gate (back door) is usually made of sheet metal, and a predetermined rigidity is ensured. However, in recent years, resin-made rear gates have been proposed from the viewpoint of weight reduction. Unlike resin-made rear gates, resin-made rear gates have a problem of reduced rigidity. In particular, in order to improve the rigidity of the door contact portion between the vehicle body rear opening panel and the resin rear gate inner panel, it is necessary to increase the plate thickness or add reinforcement reinforcement inside, resulting in weight Increased. Therefore, a back door structure has been proposed that improves the rigidity of the door-to-door portion between the vehicle body rear opening panel and the resin rear gate with a relatively lightweight reinforcement structure (see, for example, Patent Document 1 below).
JP 2000-247148 A (see FIG. 2 and paragraphs 0034 to 0036)

  The back door structure described in Patent Document 1 will be described with reference to FIG. An inner member 107 having an inner member 107 in which a reinforcing member 113 having a closed cross-sectional shape is integrated with a window frame portion 111 of an inner member 107 made of light alloy casting and a window portion 110 to which a rear window panel 108 is attached. The reinforcing member 113 is arranged from the upper part to the lower part of the window frame 111, and the reinforcing member 113 and the inner member 107 are fitted to each other. The fitting portions 117 and 119 and the fitted portions 121 and 123 to be joined together are provided separately, and the vertical rib 115 that divides the closed cross-sectional shape in the vehicle width direction is formed in the reinforcing member 113.

  With such a configuration, the reinforcing material 113 is arranged and integrated from the upper part to the lower part of the window frame part 111, so that sufficient rigidity is secured, and between the reinforcing material 113 and the inner member 107, The coupling between the fitting parts 117 and 119 and the fitted parts 121 and 123 allows the force acting between them to be reliably transmitted. As a result, even when the outer panel 105 is a resin member that satisfies only the outer plate performance such as dent resistance and tension rigidity, it is possible to secure rigidity over the hem part of the window frame part 111 and the entire window frame part 111, The increase in the number of parts and the increase in weight due to the increase in the thickness of the reinforcing material 113 and the increase in the reinforcing material can be suppressed.

  However, in the above-described conventional one, the outer panel 105 made of resin is disposed inside the inner member 107 made of light alloy casting, and the fitting portions 117 and 119 that are fitted and joined to each other between these are provided. A reinforcing member 113 composed of the fitted parts 121 and 123 is arranged, and the reinforcing member 113 is formed with vertical ribs 115 for dividing the closed cross-sectional shape in the vehicle width direction. Therefore, although the rigidity of the door contact surface of the inner member 107 made of light alloy casting is ensured, the structure is complicated, and the inner member 107 made of light alloy casting and the reinforcing material 113 made of a different material are disposed, which is a useless structure. With over quality, still causing an increase in weight.

  Therefore, the present invention solves the problems of the conventional rear gate (back door), and can secure a sufficient and necessary minimum rigidity of the door-contact surface of the resin-made rear gate with a light and simple structure. It is an object of the present invention to provide a vehicle opening / closing body seal structure.

  Therefore, the present invention provides a vehicle opening / closing body seal structure in a door contact portion between a vehicle body opening panel and a resin-made opening / closing body inner panel, along the weather strip attached to the opening panel, the door of the inner panel. A rib is formed on the back surface of the contact surface. Further, the present invention is characterized in that the rib is formed on the entire circumference along the weather strip. Further, the present invention is characterized in that the height of the rib is configured to be approximately half of the interval between the inner panel and the outer panel. Further, the present invention is characterized in that lateral ribs orthogonal to the ribs are formed at a predetermined interval. Further, the present invention is characterized in that the lateral ribs are formed so as to be inclined in the insertion progress direction of the harnesses assembled in the opening / closing body, and these are used as means for solving the problems.

  According to the present invention, in a vehicle opening / closing body seal structure in a door-contact portion between a vehicle body opening panel and a resin-made opening / closing body inner panel, the door of the inner panel extends along a weather strip attached to the opening panel. By forming the ribs on the back surface of the contact surface, the door contact surface can be effectively reinforced by a lightweight and simple reinforcing structure made of resin itself which is a material constituting the inner panel.

  Further, according to the present invention, the rib is formed on the entire circumference along the weatherstrip, so that it is reinforced by a light weight and simple structure reinforcement structure by the resin itself, which is a material constituting the inner panel, over the entire circumference of the door contact surface. It became possible to do. Furthermore, when the height of the rib is configured to be approximately half of the distance between the inner panel and the outer panel, a simple structure is sufficient by forming the minimum necessary ribs without excessive quality as a reinforcing structure. High rigidity can be maintained.

  Furthermore, by forming the transverse ribs orthogonal to the ribs at a predetermined interval, it is possible to effectively suppress the torsion of the ribs extending along the weather strip and effectively promote the reinforcing function by the ribs. it can. In addition, when the lateral rib is formed to be inclined in the insertion progress direction of the harnesses assembled in the opening and closing body, while promoting the rib reinforcing function to ensure the rigidity of the door-to-door surface along the weather strip, The insertion of harnesses assembled in the openable / closable body can be smoothly guided to improve work efficiency.
