Japanese Patent Laid-Open No. 11-245660

  As shown in FIG. 4, in the positioning structure described in Patent Document 1, the panel-side spacer 20 includes a base portion 21 that is fixed to the surface of the vehicle panel (windshield panel 25) with an adhesive such as double-sided adhesive tape, and the like. An engagement portion 22 that engages with an opening (attachment hole) of an automobile body, and a locating pin 23 that protrudes at a central position of a portion where the engagement portion 22 is formed with a larger protrusion amount than the engagement portion 22 are provided. Yes.

  However, in the positioning structure described in Patent Document 1, when the locating pin is attached to the mounting hole of the automobile body in a state of being deviated from the normal position, the shape of the locating pin is a square shape. Will be in contact. Therefore, a local concentrated load is easily applied to a part of the locate pin, and the locate pin may be deformed or damaged. Also, because the locate pin has a square shape, if the spacer is rotated and attached, it is likely to be misaligned, the vehicle panel cannot be attached to the correct position, and in the worst case it will not be assembled. There was a problem.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a vehicle panel positioning structure with improved positioning accuracy.

  That is, the present invention is a positioning structure for a vehicle panel, and includes a base portion that is bonded and fixed to the surface of the vehicle panel, and a fitting portion that is engaged with and protrudes from the base portion. The fitting portion has a circular arc-shaped outer peripheral surface substantially perpendicular to the base portion.

  In the present invention, the fitting portion may have a substantially semicircular cross section.

  Moreover, in this invention, it is preferable that the curvature radius R of the said outer peripheral surface shall be 2.0 mm or more and 8.0 mm or less.

  Moreover, in this invention, you may make it the structure which formed in the said base part the radial rib extended from the engaging part of the said fitting part and the said base part to the outer edge part of the said base part.

  Further, the base portion may be configured such that linear ribs substantially perpendicular to the longitudinal direction of the base portion are formed.

  Moreover, this invention is a vehicle panel provided with the above-mentioned positioning structure.

  According to the present invention, since the fitting portion constituting the positioning structure has an arc-shaped outer peripheral surface, the force applied to the fitting portion is easily dispersed when the vehicle panel is attached, and the portion is locally localized. Power is not added. Therefore, the vehicle panel can be attached at a normal position without the locating pin being deformed or damaged by a localized concentrated load. Further, when the spacer is rotated and attached to the glass as compared with the square locating pin, the positional deviation is reduced.

It is sectional drawing of the positioning structure which concerns on embodiment of this invention. It is a perspective view of the positioning structure which concerns on embodiment of this invention. It is a top view of the positioning structure which concerns on embodiment of this invention. It is a perspective view of the positioning structure of a prior art example.

  Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. In addition, although the vehicle panel in this invention is not specifically limited, such as glass and resin, For example, the windshield glass used as a windshield of a motor vehicle, the rear glass used for the rear part of a vehicle, etc. can be mentioned. Hereinafter, the case where a vehicle panel is used as a windshield glass will be described.

  As shown in FIGS. 1 to 3, a positioning structure 100 according to the present invention is a positioning structure 100 for a vehicle panel 22 attached to a vehicle body such as an automobile, and is used for attaching the vehicle panel 22 of the automobile body 20. The fitting part 101 inserted and fixed to the opening part 23, and the base part 16 stuck and fixed to the vehicle inner surface side of the panel 22 for vehicles are provided. The opening 23 is formed in the upper edge portion 21 of the automobile body 20.

  The fitting part 11 is integrally molded via an engaging part 15 with the base part 16, and protrudes upward from the flat surface of the base part 16. The outer peripheral surface of the fitting portion 11 has an arcuate surface that is substantially perpendicular to the base portion 16. Further, the fitting portion 11 may be configured to have a tapered projection 12 that tapers continuously toward the tip. This taper taper facilitates insertion into the mounting opening 23.

  The tapered protrusion 12 is formed with a tip apex 13 formed eccentrically from the projecting center of the fitting part 11, and has a tapered shape from the fitting part 11 to the tip apex 13. You may make it the structure which has an arc-shaped outer peripheral surface and the inclined surface 14 in an outer peripheral surface. With this inclined surface 14, the positioning structure 100 bonded and fixed to the vehicle panel can be inserted into the opening 23 not only in the vertical direction but also from an oblique direction.

  The fitting part 11 is good also as a structure which has the cavity part 17 by which the protruding center part was pulled out. The cross section of the fitting portion 11 is preferably a substantially semicircular substantially C shape. By making it into a substantially semicircular shape, the ratio of the gap of the opening 23 becomes larger when it is inserted into the opening 23 of the automobile body than in the case where it is nearly a perfect circle, so that attachment is facilitated.

  Further, by pulling out the projecting central portion, the components of the fitting portion 11 can be reduced in weight and the raw materials to be used can be reduced. Moreover, when using resin as the material of the fitting part 11, the member of the fitting part 11 can be made thin by pulling out, and the sink mark (the dent and hole by resin volume contraction) after resin molding is prevented. can do.

  The outer peripheral surface of the fitting part 11 is formed in an arc shape and has an appropriate radius of curvature, so that a local force is applied to a part of the fitting part 11 in contact with the opening 23 of the automobile body. It has no configuration. For example, it is particularly preferable that the curvature radius R of the outer peripheral surface of the fitting portion 11 is 2.0 mm or more and 8.0 mm or less, and further 2.0 mm or more and 4.0 mm or less.

  The reason is that if the radius of curvature R is greater than 8.0 mm, if the vehicle panel 22 rotates or shifts, the displacement from the normal mounting position tends to increase, which is not preferable. On the other hand, when it is smaller than 2.0 mm, it is not preferable from the viewpoint of strength such as breakage of the fitting portion 11 at the time of attachment to the automobile body 20.

  In addition, the curvature radius R said here represents the value in the contact surface of the circular-arc-shaped outer peripheral surface of the fitting part 11, and the opening part 23, as shown in FIG.

  Next, the base unit 16 will be described. The base part 16 is a substantially flat plate-like body, the base part 16 is attached to one side of the double-sided tape 30, and the other side of the double-sided tape 30 is attached to the vehicle panel 22, The part 16 is stuck and fixed. In addition, the method of sticking and fixing the base part 16 may use an adhesive such as urethane resin.

  The base portion 16 may have a structure in which a claw portion 40 for preventing the vehicle panel 22 from being reversed is provided at a corner portion of the outer peripheral edge. By providing the claw portion 40, it is possible to prevent the vehicle panel 22 from being mounted upside down.

  In addition, in order to improve the strength and flexibility of the positioning structure 100, a reinforcing rib may be formed on the base portion 16. For example, in the base part 16, radial ribs 50 a extending from the fitting part 11 and the engaging part 15 of the base part 16 toward the outer edge part of the base part 16 may be formed.

  Further, for example, a linear rib 50b substantially orthogonal to the longitudinal direction of the base portion 16 may be formed. If a plurality of the linear ribs 50b are formed in the base portion 16 so as to be bilaterally symmetric about the fitting portion 11, the strength and flexibility of the positioning structure 100 can be further improved. Here, the term “substantially orthogonal” refers to an angle that is approximately ± 90 ± 5 degrees with respect to the longitudinal direction of the base portion 16.

  The material of the base portion 16 and the fitting portion 11 constituting the positioning structure 100 is not particularly limited, such as a metal or a resin material, but from the viewpoint of moldability and processing by injection molding, such as polyacetal resin and polyethylene terephthalate. It is preferable to use engineering plastics or the like.

  The sizes of the base portion 16 and the fitting portion 11 constituting the positioning structure 100 should be appropriately changed depending on the vehicle panel 22 used and the type of the automobile body. For example, as a suitable size, the base portion 16 may be configured such that the longitudinal direction is 50 mm or more and 150 mm or less and the lateral direction is 10 mm or more and 30 mm or less. This numerical range is preferable because sufficient adhesive strength can be easily obtained in the pulling direction and the displacement direction. Moreover, it is preferable that the height of the fitting part 11 shall be 5.0 mm or more from a viewpoint of attachment ease and intensity | strength.

  Moreover, according to the above embodiment, there exists the effect shown below.

  In the positioning structure 100 according to the present invention, the fitting portion 11 has an arc-shaped outer peripheral surface substantially perpendicular to the base portion 16. For this reason, even when the vehicle panel 22 is attached with a displacement, the local concentrated load is hardly applied to a part of the fitting portion 11. Therefore, the positioning structure 100 of the present invention can prevent the positioning structure 100 from being damaged by a concentrated load, and has an advantage from the viewpoint of strength.
