Description

  The present invention relates to a cowl top cover that covers a cowl top portion between a front window glass and a front hood (bonnet), and in particular, the connection of two adjacent panels of a cowl top cover configured by combining a plurality of panels. Concerning structure.

  2. Description of the Related Art Conventionally, a cowl top portion of an automobile is provided with an air inlet for taking outside air into a passenger compartment, a drive shaft for driving a wiper, and the like. In order to protect these and prevent the intrusion of rainwater and dust, a cowl top cover that covers the cowl top is attached to the upper surface of the cowl top over substantially the entire vehicle width.

  The body of the cowl top cover is molded from a synthetic resin material. Conventionally, an elongate unit covering almost the entire vehicle width has been used. For example, the cowl top cover is bent along the curved surface of the front window glass and the right and left ends of the vehicle body. Since a shape that gradually increases the front-rear dimension toward the part is required, a cowl top cover that uses a plurality of panels divided in the vehicle width direction has come to appear. .

Such cowl top covers include those disclosed in Patent Document 1 and Patent Document 2, for example.
Japanese Patent Laid-Open No. 5-96935 (paragraphs 0014-0030, FIG. 1, to FIG. 2) Japanese Patent Laid-Open No. 10-119821 (paragraphs 0009-0014, FIG. 1, etc.).

  According to Patent Document 1, the cowl top cover is formed in two left and right halves by dividing the main body into left and right parts in the vehicle width direction. The left and right halves intermittently have claw portions that support the lower edge of the front window glass along the rear edge.

  Further, the front end edge of each half has a standing wall portion and a mounting piece extending from the upper edge of the standing wall portion to the front of the vehicle body, and a pin projects from the lower surface of the mounting piece. In the cowl top portion, a mounting hole having a long hole shape is formed in the vehicle width direction in order to insert the pin at a position corresponding to the pin.

  A flange having a substantially L-shape is extended from the end edge of the right half portion with the end position shifted forward and downward, and the flange extends in the longitudinal direction of the vehicle body. A long hole is formed to extend to.

  A pin is projected from the connecting edge of the left half at a position corresponding to the long hole, and the left half is overlapped with the flange upper surface of the right half. The long hole is inserted and positioned, and both are connected.

  The right half part is attached to the vehicle body by inserting the pin of the attachment piece into the attachment hole of the cowl top part and fitting the lower end part of the front window glass into the claw part.

  Next, the pin projecting from the connection side edge of the left half is inserted into the long hole formed in the longitudinal direction of the vehicle body on the flange of the right half, and the left half is While moving in the direction, the lower edge of the front window glass is fitted and attached to the vehicle body.

  At this time, the pin formed in the attachment portion of the left half is further inserted into the attachment hole of the cowl top portion, and the left half is positioned with respect to the vehicle body.

  However, the attachment of the cowl top cover to the vehicle body is only partially supported by the claw portion formed at the rear edge of the cowl top cover body, and the cowl top cover is also supported by the lower end edge of the front window glass. The pins projecting from the front end edge of the main body are merely inserted into the mounting holes of the cowl top portion and positioned with respect to the vehicle body, and thus are not restricted in the vertical direction and the front-rear direction of the vehicle body.

  Therefore, the cowl top cover is formed in an overall plate shape, and particularly when the mesh-shaped opening is formed integrally or separately, the cowl top cover may be twisted and wavy even after being attached to the vehicle body. As a result, a gap is generated between the connecting parts, the appearance is deteriorated, dust and dead leaves enter the cowl top through the gap, and enter the air conditioning box from the air intake on the vehicle body side. In other words, problems such as blocking the drainage of rainwater remain unsolved.

  Therefore, in order to solve the above problems, a cowl top cover disclosed in Patent Document 2 has been proposed.

  According to Patent Document 2, the cowl top cover is divided into two parts, a right half part and a left half part, and the right half part has a step from the back side of the connecting side edge with the left half part, and the back side of the left half part. A plate-like connecting portion that abuts is extended.

  On the other hand, the left half portion is parallel to the connection side edge in the vicinity of the back surface in contact with the connection portion, that is, from the connection side edge of the left half portion to the other end edge side slightly longer than the length of the connection portion. A protruding ridge is formed.

  Therefore, since the protrusion is formed in the vicinity of the connection side edge of the left half, the shape of each edge is maintained even when the entire cowl top cover is deformed over time, such as waving. It is intended to prevent deformation.

  However, in the cowl top cover disclosed in Patent Document 2, the protrusion on the left half side does not contact the edge of the connecting portion on the right half side. It can be said that the vertical direction of the vehicle body is not restricted without any gap in the half of the connecting part. There is a possibility that a gap will occur at the edge. If a gap occurs, the appearance may be damaged, and it is possible to prevent dust and dead leaves from entering the cowl top from the gap. There was also a fear of not.

In order to solve the above-described problem, a cowl top cover disclosed in Patent Document 3 is known.
Japanese Patent Laid-Open No. 10-211891 (paragraphs 0016-0031, FIG. 7, etc.).

  The cowl top cover described in Patent Document 3 is configured so that connecting portions are formed in the left and right halves of the cowl top cover body, and the connecting side edges of the left and right halves are connected.

  That is, the connecting portion at the connecting side edge of the left half has a rectangular opening formed in the main body portion of the connecting portion, and the three side walls that open the connecting side wall portion around the back of the opening. The bottom of the box-shaped recess is formed with a long hole along the vehicle width direction.

  The right half of the connecting portion is formed of an L-shaped connecting piece formed so as to place the bottom portion at a position corresponding to the box-shaped recess, and the horizontal portion of the connecting piece has a vehicle width direction. A long hole is formed along.

  And by inserting the clip-like connecting piece portion of the connecting member into the long holes, the left and right half portions are regulated in the vehicle body vertical direction, and the head is positioned at one end of the connecting piece portion of the connecting member. A portion is formed, and the opening of the box-shaped recess is closed by the head.

  However, in the cowl top cover described in Patent Document 3, the clip-like connecting piece portions of the connecting members are fitted into the long holes provided in the left and right half portions, so that the left and right half vehicle body vertical directions In order to adopt the configuration of performing the regulation of the vehicle, the coupling piece portion reliably restricts the vehicle body vertical direction and the horizontal direction at the connecting portion of the left and right half portions, while the left and right half portions are deformed over time, etc. When a force in the longitudinal direction of the vehicle body is applied relatively, there is a risk that the left and right half parts will move relative to each other with the connecting piece portion as an axis. I can say that.

  Therefore, in view of such a point, the present invention reliably restricts two adjacent panels of a cowl top cover configured by combining a plurality of panels not only in the lateral direction and the vertical direction of the vehicle body but also in the longitudinal direction of the vehicle body. It aims at providing the connection structure made into a structure.

  In order to achieve the above object, a connection structure according to the present invention described in claim 1 is a connection structure for connecting two adjacent panels of a cowl top cover formed by combining a plurality of panels, A first advancing / retreating position restricting means for restricting a relative advancing / retreating position of the two panels in one direction among a direction, a left-right direction, and a front-rear direction; A second advancing / retreating position restricting means for restricting the relative advancing / retreating position of the two panels in the direction, and at least one of the other panels in the up / down direction, the left / right direction, and the front / rear direction. A third advance / retreat position restricting means for restricting the relative advance / retreat position is provided.

  According to the present invention configured as described above, in the connecting portion between two adjacent panels, the first forward / backward position restricting means among the two panels in one direction among the vertical direction, the horizontal direction, and the front-rear direction. The relative advance / retreat position is restricted, the relative advance / retreat position of the two panels is restricted in the other direction by the second advance / retreat position restricting means, and further the other one direction by the third advance / retreat position restricting means. The relative advancing and retreating positions of the two panels are regulated in at least one direction, so that the two split cowl top cover pieces are relatively deformed in the vertical direction of the vehicle body, the longitudinal direction of the vehicle body, and the lateral direction of the vehicle body. Even if it tries to deform, the deformation force is received by the first to third advance / retreat position restricting means, and a gap or the like in the connecting portion is not generated, and the appearance is damaged. And without and may be dust, dead leaves or the like is reliably prevented from entering the inside the cowl top.
