Description

  The present invention relates to an automobile molding mounting structure, and more particularly to a molding mounting structure arranged for decoration purposes in a parting portion between a front pillar and a rear upper end of a front fender.

  For example, Patent Document 1 has proposed a mounting structure for this type of molding.

  In the structure described in Patent Document 1, a flange portion is formed on the rear upper end portion of the front fender toward the front pillar side, and a parting portion (butting portion) between the rear upper end portion of the front fender and the front pillar is provided. ) To be concealed as a whole, the molding arranged in the parting portion is generally plate-shaped. And the engaging part which becomes the base part of the molding is engaged with the flange part, and the molding lip part which extends right above the engaging part is bonded and fixed to the outer surface of the front pillar with a double-sided adhesive tape (adhesion) )

JP 2012-1193 A

  However, since the structure described in Patent Document 1 is a system in which the molding lip is joined and fixed with a double-sided adhesive tape, there is a problem that the cost is increased with an increase in the number of parts and the assembling workability is poor. That is, in the structure described in Patent Document 1, the engaging portion that is the base portion of the molding is engaged with the flange portion of the rear upper end portion of the front fender side and positioned at the normal position, and then the back surface of the molding lip It is necessary to peel the release paper of the double-sided pressure-sensitive adhesive tape that has been attached in advance to press the molding lip against the front pillar, and the assembling workability is extremely poor.

  The present invention has been made paying attention to such a problem, and particularly provides a molding mounting structure capable of remarkably improving the assembly workability while reducing the number of parts and the cost by eliminating the double-sided adhesive tape. Is.

  Therefore, the present invention adopts a so-called gripping method to the flange portion at the rear upper end portion of the front fender while pressing the mounting main body portion of the molding to the front pillar side as a supporting form of the molding, and is formed to protrude from the mounting main body portion. The mold lip is pressed against the front pillar by its self-elasticity.

  More specifically, the invention according to claim 1 is a vehicle body longitudinal direction between a front pillar of an automobile body and a rear upper end portion of the front fender that is close to the front pillar from the outside in the vehicle width direction. It assumes the mounting structure of the mall that is installed along. A flange portion for positioning and supporting the molding is bent at the rear upper end portion of the front fender, and the flange portion includes a root-side bent piece portion bent downward and the root-side bent piece portion. Are bent into a substantially crank shape in cross section by a shelf-like portion bent toward the front pillar side and a tip-side bent piece portion bent downward from the shelf-like portion.

  On the other hand, the molding has a substantially U-shaped cross-section that sandwiches the shelf-like portion and the tip-side bent piece portion from above and below while contacting each of the base-side bent piece portion, the shelf-like portion, and the tip-side bent piece portion of the flange portion. Mounting main body, a molding lip projecting obliquely upward from the mounting main body toward the front pillar side, and pressing against the front pillar, and the molding lip on the inner surface of the mounting main body facing the front pillar. A posture-holding lip that protrudes obliquely downward from the lower position of the head and presses against the front pillar, and a guide protrusion that protrudes from the lower end portion of the mounting base portion toward the outdoor portion rather than the tip-side bent piece portion. And.

  In addition, a gap is formed between the front pillar and the inner surface of the mounting main body on the front pillar side.

  As a further specific structure of the mounting and holding portion, as described in claim 2, the mounting and holding portion includes an upper holding portion that abuts on a base-side bent piece portion and a shelf-like portion of the flange portion, and a flange portion. A lower holding portion that comes into contact with the distal end of the distal-side curved piece portion in the contact, and a connection that is located between the upper holding portion and the lower holding portion and comes into contact with the front pillar-side surface of the distal-end curved piece portion in the flange portion And the guide protrusion is formed at the tip of the lower holding portion.

  In order to further improve the assembling workability, as described in claim 3, the distance formed by the leading-end-side bent piece portion of the flange portion and the guide projection portion in the vehicle width direction is set to the shelf of the flange portion. It is desirable that the width is set to be smaller than the overlapping width in the vehicle width direction between the shape portion and the upper holding portion of the attachment holding portion.

  More preferably, as described in claim 4, a reinforcing block is partially provided along the longitudinal direction on the inner surface of the mounting main body on the front pillar side, and a gap formed between the reinforcing block and the front pillar is It is assumed that the front end side bent piece portion of the flange portion and the guide projection portion are set to have substantially the same size as the distance formed in the vehicle width direction.

  Furthermore, in order to make the positioning of the molding more reliable and prevent its displacement, end cap parts are formed at the front end and the rear end in the longitudinal direction of the molding lip as described in claim 5. It is desirable.

  More preferably, as described in claim 6, a positioning block that contacts the end of the front fender is formed at the longitudinal front end of the upper holding portion of the mounting main body.

  Therefore, in at least the first aspect of the invention, the mounting main body portion is so-called sandwiched into the flange portion at the rear upper end portion of the front fender while the posture maintaining lip formed on the mounting main body portion of the molding is pressed against the front pillar side. By adopting the system, the molding is positioned, and the molding lip protruding from the mounting base is pressed against the front pillar by its self-elastic force, and the state is stably maintained for a long time. Thereby, a double-sided adhesive tape is not required.

  According to the present invention, since a double-sided adhesive tape is not required as a means for fixing the molding, the number of parts and cost can be reduced, and a gap is provided between the front pillar and the inner surface of the mounting main body on the front pillar side. Since the guide protrusion is formed on the mounting main body, the workability at the time of assembling is improved and the assembling workability is remarkably improved.

  In addition, the reaction force caused by the pressure contact of the molding lip or posture holding lip against the front pillar acts in the direction of pressing the mounting body against the flange on the front fender, creating a gap between the flange and the mounting body. If it is not done, the mall will not be broken or dropped, the appearance around the mall will be good, and the appearance quality will be improved.

  As shown in FIG. 1 and FIG. 2, a rear upper end portion of the front fender 2 is abutted with a predetermined step and a gap at a portion corresponding to a so-called waist height position of the front pillar 1, and the front pillar 2 and the front fender. 2 between the front pillar 1 and the rear upper end of the front fender 2 in the longitudinal direction of the vehicle body so as to conceal the butting part (parting part) with the rear upper end of the vehicle 2 and avoid interference between them. 7 is installed. The molding 7 is formed of a resin material or a rubber-based material and has a predetermined flexibility, and is sandwiched between the front pillar 1 and the rear upper end of the front fender 2 as shown in FIG. The positioning is fixed. In the regular assembly state of the molding 7 shown in FIG. 1, the longitudinal length of the molding 7 is aligned and matched with the longitudinal length of the front pillar 1 at the corresponding portion.

  As shown in FIG. 2, a flange portion 8 is formed at the rear upper end portion of the front fender 2 so as to be folded back toward the front pillar 1 side. The flange portion 8 includes a root-side bent piece portion 8a bent downward, a shelf-like portion 8b bent substantially horizontally from the root-side bent piece portion 8a toward the front pillar 1 side, and the shelf-like portion. It is bent and formed in a substantially crank shape in cross section by a distal end side bent piece portion 8c bent further downward from 8b. As a result, in the normally assembled state of the molding 7 shown in FIG. 2, the fitting groove 9d on the mounting body 9 side sandwiches the flange portion 8 having the substantially crank-shaped section from above and below as shown in FIG. Thus, the molding 7 is positioned and held on the front fender 2.

  4 to 7 show details of the molding 7 alone shown in FIGS. 1 and 2, FIG. 4 is a perspective view seen from the same direction as FIG. 1, and FIG. 5 is an overhead view of the molding 7 of FIG. The top perspective views are shown respectively.

  As shown in FIGS. 4 and 5 in addition to FIG. 2, the molding 7 has a deformed belt shape which is long in the longitudinal direction of the vehicle body as a whole, and in the free state as shown in FIGS. It is smoothly curved into an arc shape so as to have a convex shape. The molding 7 is roughly divided into a mounting main body 9, a molding lip 10 that projects obliquely upward from a position near the front pillar 1 in the mounting main body 9, and a front pillar of the mounting main body 9. A posture holding lip 11 is formed so as to project obliquely downward from a position lower than the projecting position of the molding lip 10 on one side inner surface (the inner surface facing the front pillar 1).

  As shown in FIG. 2, the attachment main body portion 9 has a substantially U-shaped cross section with a thick upper holding portion 9 a and a lower holding portion 9 b and a connection portion 9 c interposed therebetween. The U-shaped inner space is formed as a fitting groove 9d for the front fender 4 described later. And the taper part 9e is formed in the corner | angular corner part which faces the open side of the fitting groove 9d among the upper side holding | maintenance parts 9a, and the site | part which faces the open side of the fitting groove 9d among the lower side holding parts 9b. A guide projection 9f including a tapered surface is formed to protrude upward. Due to the presence of the tapered surface 9e and the guide projection 9f, the fitting groove 9d of the mounting main body 9 is opened obliquely upward in a so-called stepped shape, not in a lateral direction.

  As is apparent from FIG. 4, the upper holding portion 9a of the mounting main body portion 9 is formed as a so-called eaves-like shape having a predetermined width when viewed from the overhead view, and particularly the width at the front end side. The dimensions are formed so as to gradually increase toward the front side.

  In addition, as shown in FIG. 2, a reinforcing block is provided on the inner surface of the mounting main body 9 on the front pillar side and at a position corresponding to the root portion of the molding lip 10 and the root portion of the posture holding lip 11. 12 is formed. 6 is a perspective view of the molding 7 shown in FIG. 4 as seen from the back side. As is apparent from FIGS. 2 and 6, the inner surface of the mounting body 9 on the front pillar 1 side is A plurality of reinforcing blocks 12 are partially formed along the longitudinal direction, that is, the reinforcing blocks 12 protrude intermittently at a predetermined pitch at a plurality of locations.

  As shown in FIG. 2, the molding lip 10 has a tongue-like shape in which the thickness in the lip projecting direction gradually decreases from the base portion on the mounting main body 9 side toward the distal end side. As shown by a broken line, the curve is curved in an arc shape so as to be convex in the clockwise direction (right side). As shown in FIG. 6 in addition to FIGS. 4 and 5, end cap portions 10a and 10b are formed at the front end and the rear end in the longitudinal direction of the molding lip 10, respectively.

  On the other hand, as shown in FIG. 2, the posture holding lip 11 has a wall thickness smaller than that of the molding lip 10 and substantially constant over the entire length of the lip protruding length. Then, it is curved in an arc shape so as to be convex toward the clockwise side (right side) in FIG.

  Further, FIG. 7 shows an enlarged view of the main part when the front end portion of the molding 7 shown in FIG. 4 is viewed in an elevational manner, and FIG. 8 shows an enlarged cross-sectional view along the line CC in FIG. Yes. As shown in FIGS. 7 and 8, a positioning block 13 extending in the width direction of the upper holding portion 9a is formed in a bead shape on the back surface of the upper holding portion 9a at the front end portion of the mounting main body portion 9. . The positioning block 13 is in contact with and engaged with the end of the front fender 4 as shown in FIG. Positioning in the longitudinal direction is performed.

  In the normal assembly state of the molding 7 shown in FIG. 2, the flange 8 on the front fender 4 side is sandwiched from above and below by the fitting groove 9 d of the mounting body 9, thereby Both are positioned relative to each other, and the molding 7 is fitted and held on the flange portion 8 of the front fender 4. More specifically, the upper holding portion 9a of the mounting main body 9 abuts on the base-side bent piece portion 8a and the shelf-shaped portion 8b of the flange portion 8, respectively, and the connection portion 9c of the mounting main body portion 9 is on the distal end side of the flange portion 8. Abutting the surface of the bent piece portion 8c on the front pillar 1 side, and the lower holding portion 9b of the attachment main body portion 9 abutting on the front end of the front end side bent piece portion 8c of the flange portion 8, The fitting groove 9d is fitted and held so as to hold the flange portion 8 therebetween.

  As a result, the posture holding lip 11 and the molding lip 10 that are formed to protrude from the attachment holding portion 9 are bent and deformed so as to follow the front pillar 1, respectively, and come into pressure contact with the outer surface of the front pillar 1.

  In this case, the end cap portions 10a and 10b formed by bending at both ends in the longitudinal direction of the molding lip 10 are in close contact with the front and rear ends of the front pillar 1, and the position of the molding 7 in the longitudinal direction is restricted. (See FIG. 3), as shown in FIG. 8, the positioning projection 13 on the back surface of the upper holding portion 9a of the mounting main body 9 is fitted so as to drop into the end of the front fender 4, and this also The molding 7 is positioned in the longitudinal direction. Note that the presence of the end cap portions 10a and 10b can also contribute to an improvement in appearance when the molding 7 is viewed from the front-rear direction.

  In the normal assembly state of the molding 7 as shown in FIG. 2, between the inner surface of the mounting body 9 of the molding 7 on the front pillar 1 side and the front pillar 1, and the molding lip 10 and the posture holding lip 11. If a gap G is secured in the portion excluding the respective front end portions and the reinforcing block 12 formed on the inner surface of the mounting main body 9 on the front pillar 1 side is used as a reference, the reinforcing block 12 and the front The gap between the pillars 1 is T3. In addition, a gap T2 is secured between the distal end side bent piece portion 8c of the flange portion 8 fitted in the fitting groove 9d of the attachment main body portion 9 and the guide projection portion 9f of the lower holding portion 9b. In addition, the relationship between the gaps T2 and T3 is set such that T2≈T3 so that the two are substantially equivalent. Further, T1> T2 is set so that T2 is smaller than T1 when T1 is a running margin of the upper holding portion 9a with respect to the shelf-like portion 8b of the flange portion 8.

  As described above, the gap between the front pillar 1 and the rear upper end of the front fender 4 is concealed so as to be filled with the molding 7, and particularly, as shown in FIG. A part of the main body portion 9 and the molding lip 10 give design and improve design.

  In this case, the reaction force accompanying the pressure contact of the molding lip 10 and the posture maintaining lip 11 with respect to the front pillar 1 acts in the direction of pressing the mounting body 9 against the flange 8 on the front fender 2 side. If there is no gap between the main body portion 9 and the mall 7, the so-called blinking or sinking of the mall 7 does not occur, and the appearance around the mall 7 is good. Quality will also improve.

  Here, when the molding 7 is assembled, as shown in FIG. 9, the molding 7 is inserted between the front pillar 1 and the rear upper end of the front fender 2 with the rear end side of the molding 7 as the insertion start end side. Suppose that it pulls in the vehicle body back side along the flange part 8 shown in FIG. At that time, as shown in FIG. 10, although the fitting groove 9 d of the mounting main body 9 is fitted to the flange portion 8 of the front fender 2, the mounting main body 9 is pressed against the front pillar 1 and the upper holding portion is used. 9a is separated from the bent side 8a of the flange 8 and the molding lip 10 is lifted in the direction of arrow D in FIG. 10 to secure a gap with the front pillar 1 as described above. It is assumed that 7 as a whole is pulled in the rear side of the vehicle body. By doing so, the molding 7 can be smoothly assembled while reducing the sliding resistance between the flange portion 8 and the attachment main body portion 9.

  In this case, as shown in FIG. 2, since the relationship between the dimension T2 and the dimension T3 is set to T2≈T3, the molding lip 10 is rolled while the mounting body 9 is pressed against the front pillar 1 side. Even if it is separated from the front pillar 1 by raising, the lower posture holding lip 11 is pressed against the front pillar 1 and generates a predetermined reaction force, so that the posture of the molding 7 is stably supported. Thus, the mounting main body 9 does not cause a so-called falling phenomenon or fall downward when the molding is assembled.

  Further, even if the mounting main body 9 is pressed against the front pillar 1 as described above, the relationship between the dimension T1 and the dimension T2 is set as T1> T2, as shown in FIG. The upper support part 9a of the main body part 9 is not detached from the shelf-like part 8b of the flange part 8, and the assembly workability can be maintained satisfactorily.

  As described above, according to the present embodiment, the molding 7 can be assembled without using a double-sided adhesive tape or the like while maintaining the assembly workability satisfactorily. The assembled state can be stably maintained.
