Description

[Technical field]

[0001] The present invention relates to a connection structure between a door outside molding attached to a waist portion of a door of an automobile and a base member of a door mirror. [Background technology]

[0002] For example, a door outside molding (hereinafter referred to as molding) is attached along the door belt line near the waist of the outside of the front door of an automobile. This molding guides the door glass when it is opened and closed, and has the function of wiping off water droplets such as rainwater and car wash water and dust that adhere to the door glass. It also functions to improve the appearance quality as part of the design of the front door.

[0003] A known mounting structure for the molding is described in the following Patent Document 1. As shown in Fig. 11, this molding 1 is an extrusion molded product of synthetic resin material with a metal insert plate 2 embedded therein, and has an inverted U-shaped base 3 and seal lips 4, 5 that are provided on the inner surface of the inner wall 3a of the base 3 in two stages, one above the other, and come into contact with the outer surface of the door glass G. The base 3 is attached to a mounting flange 9, which is joined to an outer panel 7 of an automobile door and a reinforcement 8 parallel to the door glass G, via a clip 6 made of synthetic resin.

[0004] The clip 6 is embedded in the base 3 in advance, and when the molding 1 is attached to the mounting flange 9 in this state, the locking protrusion 6a formed on the clip 6 fits into the mating hole 9a in the mounting flange 9, thereby attaching the molding 1 to the mounting flange 9.

[0005] Other mounting structures include, for example, a structure described in Patent Document 2 in which, without using clips, the molding is fitted to cover the upper edge of the door outer panel, and an end piece provided at the end of the molding is fixed to the lower end of the door frame by screws.

[0006] On the other hand, a door mirror is disposed at a position in front of the front door, and this door mirror has a base member fixed to the door panel, and one end of the molding on the longitudinal front side of the vehicle body is disposed opposite this base member.

[0007] [Patent Document 1] JP 9-27782 A (Fig. 5) [Patent Document 2] Patent No. 3412490 Summary of the Invention [Problem to be solved by the invention]

[0008] However, the conventional mounting structures for each molding are directed to a structure for mounting the molding to a door panel or door frame, and no consideration is given to the connection structure between one longitudinal end of the molding and the door mirror.

[0009] Therefore, if the conventional molding mounting structure is applied as is, there is a risk that a gap will occur between one end of the molding and the base member of the door mirror that it faces, or that one end of the molding will be inserted inside the base member of the door mirror, creating a step.

[0010] In this way, if a gap or step occurs between one end of the molding and the base member of the door mirror, the unity between the two will be lost and the appearance will be impaired, which may result in a decrease in the appearance quality.

[0011] The present invention has been devised in consideration of the technical problems associated with the conventional molding mounting structures, and aims to provide a connecting structure between a door outside molding and a door mirror that can suppress the occurrence of gaps or steps between the two by connecting one end of the molding to the base member of the door mirror via a connecting plug. [Means for solving the problem]

[0012] The invention described in claim 1 of the present application is a connection structure that connects one end of a door outside molding in a longitudinal direction, which is attached to a door waist portion of an automobile, to a base member of a door mirror via a connection plug, the door west side molding has a first insertion hole into which one end of the connecting plug in the longitudinal direction can be inserted, and a first locking hole is formed in a peripheral wall defining the first insertion hole, the base member has a second insertion hole into which the other end of the connection plug in the longitudinal direction can be inserted, and a second locking hole is formed in a peripheral wall defining the second insertion hole, The connecting plug is characterized in that it has, at one longitudinal end, a first locking portion that is elastically deformable in inward and outward directions to engage with the edge of the first locking hole when the one end is inserted into the first insertion hole, and, at the other longitudinal end, a second locking portion that is elastically deformable in inward and outward directions to engage with the edge of the second locking hole when the other end is inserted into the second insertion hole. Effect of the Invention

[0013] According to the invention described in claim 1 of the present application, by connecting one longitudinal end of the molding to the base member of the door mirror with a connecting plug, the occurrence of gaps and steps between the two is suppressed, a sense of unity is obtained, and the appearance is improved, resulting in an improved external quality.

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a door exterior molding and door mirror connection structure according to the present invention will be described with reference to the drawings.

[0016] FIG. 1 is an oblique view showing the left side of the door mirror of an automobile to which the door outside molding and door mirror connecting structure of the present invention is applied; FIG. 2 is an oblique view showing the state in which one end of the door outside molding in this embodiment and the end of the base part of the door mirror are connected by a connecting plug; FIG. 3 is an oblique view showing the state before one end of the connecting plug is inserted into the first insertion hole of the molding used in this embodiment; FIG. 4 is an oblique view showing the state before the other end of the connecting plug, one end of which is inserted into the first insertion hole of the molding used in this embodiment, is inserted into the second insertion hole of the base member of the door mirror; and FIG. 5 is a cross-sectional view along line AA of FIG. 4.

[0017] As shown in FIG. 1, a door outside molding (hereinafter referred to as molding) 11 is arranged along the fore-and-aft direction of the vehicle body at the waist portion of a door body 10a of an automobile front door 10, and a door mirror 12 is arranged at the front end portion of the door body 10a.

[0018] As shown in Figure 5, the molding 11 is an extrusion-molded product of synthetic resin with a metal insert plate 11b embedded inside, and has a base 13 with a substantially inverted U-shaped cross section, sealing lips 14, 15 provided in two levels, one above the other, on the inner surface of the inner wall 13a of the base 13 and abutting the outer surface of the door glass not shown, and a metal-plated molding portion 16 fitted and fixed to the outer part of the base 13.

[0019] As shown in Figures 3 to 5, the base 13 has a first insertion hole 17 formed in the longitudinal direction in the internal axial direction. One end 22a of a connecting plug 22 described later is inserted into this first insertion hole 17, which is formed with an inverted U-shaped cross section similar to the cross section of the one end 22a and extends toward the rear of the vehicle. The inner wall 13a is provided at its lower end with an abutment portion 13c that abuts against the outer surface of a reinforcement (not shown), and a support portion 13d that supports the lower end surface of one side wall 24 of the connecting plug 22 is protruded from the approximately vertical center of the inner surface.

[0020] The outer wall 13b of the base 13 is formed so that its vertical length is shorter than that of the inner wall 13a, and the folded portions 16a, 16b provided at the upper and lower ends of the molding portion 16 are fitted and fixed into first and second fitting grooves 13e, 13f formed along the longitudinal direction at the upper and lower ends.

[0021] A first locking hole 18 for locking with a first locking portion 26 provided at one end 22a in the longitudinal direction of a connecting plug 22 (described later) is formed radially through the inner wall 13a at a position above the support portion 13d.

[0022] 3 and 4, the first locking hole 18 is provided at a predetermined position corresponding to a first locking portion 26 of one end 22a of a connecting plug 22 inserted into the first insertion hole 17 from one end 11a side in the longitudinal direction of the molding 11. The first locking hole 18 is formed in a rectangular shape that is long in the longitudinal direction, and has a linear first hole edge portion 18a on the inner end side and a linear second hole edge portion 18b on the outer end side that face each other in the longitudinal direction.

[0023] The molding 11 is attached, at a portion of the base 13 of one end 11a other than the side facing the door mirror 12, to a mounting flange that joins the outer panel of the door body 10a of the front door 10 and a reinforcement (not shown) that is parallel to the door glass, by means of mounting members such as clips or bolts.

[0024] As shown in Figures 1 and 2, the door mirror 12 has a base member 19 fixed to the front end of the front door 10 by a bolt or the like (not shown), and a mirror body 12a supported by the base member 19.

[0025] As shown in Fig. 4, the base member 19 is integrally formed of a synthetic resin material in a different shape, and a second insertion hole 20 is formed toward the front of the vehicle body inside an end 19a where one end 11a of the molding 11 is butted in the axial direction. The second insertion hole 20 is axially inserted with the other end 22b of a connecting plug 22, which will be described later, and is formed in an inverted U shape similar to the cross-sectional shape of the other end 22b of the connecting plug 22. As shown in Fig. 4, the second insertion hole 20 is formed so that the width L1 is smaller than the width L (see Fig. 3) of the first insertion hole 17.

[0026] Further, a second locking hole 21 for receiving a second locking portion 27 provided at the other end 22b of the connecting plug 22 is formed through the side wall portion 19b constituting the second insertion hole 20 of the base member 19 in the radial direction.

[0027] 4, the second locking hole 21 is provided on the same surface as the first locking hole 18 at a predetermined position corresponding to the second locking portion 27 of the other end 22b of the connecting plug 22 of the second insertion hole 20. The second locking hole 21 is formed in a rectangular shape that is long in the longitudinal direction, and has a linear first hole edge portion 21a on the inner end side and a linear second hole edge portion 21b on the outer end side that face each other in the longitudinal direction (see FIGS. 7 and 8).

[0028] The above-mentioned connecting plug 22 is inserted into the first insertion hole 17 of the molding 11 and the second insertion hole 20 of the base member 19 of the door mirror 12 .

[0029] Figure 6 shows a connecting plug used in this embodiment, where (a) is an overhead view of the connecting plug, (b) is a left side view of the connecting plug, and (c) is a plan view of the connecting plug. Figure 7 is a vertical cross-sectional view showing the state in which one end of the molding and the end of the base member of the door mirror are connected by the connecting plug used in this embodiment. Figure 8 is a partial enlarged view of Figure 7, where (a) is an enlarged vertical cross-sectional view showing the state in which one end of the molding and the end of the base member of the door mirror are connected by the connecting plug used in this embodiment, (b) is an enlarged view of part B in (a), and (c) is an enlarged view of part C in (a).

[0030] As shown in Figures 6(a) to (c), this connecting plug 22 is made of synthetic resin material and has an inverted U-shaped cross section, has a predetermined length along the longitudinal direction, and is arranged so that one end 22a in the longitudinal direction is inserted into the first insertion hole 17, and the other end 22b is inserted into the second insertion hole 20, with approximately half of the longitudinal direction being inserted therein.

[0031] The connecting plug 22 has an arc-shaped top 23 and both side walls 24, 25 extending downward in parallel from both end edges of the top 23, with the one side wall 24 on the vehicle outer side extending further downward than the other side wall 25 on the vehicle inner side. The width W between the two outer surfaces of the both side walls 24, 25 is set to be approximately the same as or slightly larger than the width length L1 of the second insertion hole 20, so that when the other end 22b is inserted into the second insertion hole 20, the entire outer surface of the other end 22b is inserted into the inner surface of the second insertion hole 20 with slight sliding resistance.

[0032] The one side wall 24 is provided with a first locking portion 26 and a second locking portion 27 on the outer surface of the one end 22a side and the other end 22b side of the connecting plug 22. The first locking portion 26 and the second locking portion 27 are provided in a form cut and raised from the openings 24a, 24b formed in the one side wall 24, and are formed so that the tip portions 26b, 27b side rise from the base ends 26a, 27a toward the outside of the vehicle in an inclined manner, and the tip portions 26b, 27b are arranged in a direction facing each other. In other words, the base ends 26a, 27a are arranged in opposite directions to each other, and the tip portions 26b, 27b extending from the base ends 26a, 27a are arranged to face each other. In addition, the first and second engagement portions 26, 27 are formed so that the tip portions 26b, 27b can elastically deform in the inside-outside direction (radial direction) of the vehicle, with the base ends 26a, 27a as fulcrums. When elastically deformed inward, the entire portion is contained within the openings 24a, 25a, and when elastically deformed outward, the tip portions 26b, 27b protrude outward from the openings 24a, 25a.

[0033] Each of the tip portions 26b, 27b is formed to have a thick cross section, and claw portions 26d, 27d are respectively protruded from the inner end edges of the first and second tip surfaces 26c, 27c, and the tip surfaces 26c, 27c are formed to be inclined upward from the outer end edges toward the claw portions 26d, 27d. In other words, each of the tip surfaces 26c, 27c is not flat, but is formed to be inclined upward at a predetermined angle from the outer end edges on the outer surface side toward the claw portions 26d, 27d with respect to the outer surfaces of the locking portions 26, 27. When each engagement portion 26, 27 engages with each first hole edge portion 18a, 21a of each engagement hole 18, 21, each claw portion 26d, 27d engages with the lower end edge of the corner edge 18c, 21c of each hole edge portion 18a, 21a, thereby restricting the elastic deformation and movement of each tip portion 26b, 27b toward each engagement hole 18, 21.

[0034] As shown in FIG. 8(a), the separation distance T between the first hole edge portions 18a, 21a on the inner end sides of the first engagement hole 18 and the second engagement hole 21 is set to a length such that when both ends 22a, 22b of the connecting plug 22 are inserted into the respective insertion holes 17, 20, the respective end faces 26c, 27c of the respective end portions 26b, 27b of the first engagement portion 26 and the second engagement portion 27 are engaged with the respective corner edges 18c, 21c of the first and second hole edges 18a, 21a of the first and second engagement holes 18, 21.

[0035] 6, the connecting plug 22 is provided with a protrusion 28 at a position corresponding to the first locking portion 26 on the outer surface of the other side wall 25. The protrusion 28 is formed to fill the difference in width length, since the width length L of the first insertion hole 17 is larger than the width length L1 of the second insertion hole 20, and is formed in a long and thin block shape along the longitudinal direction of the connecting plug 22. When the one end 22a of the connecting plug 22 is inserted into the first insertion hole 17, the flat upper end surface 28a abuts against the inner surface of the outer wall 13b of the base 13 constituting the first insertion hole 17, thereby preventing a decrease in the elastic reaction force of the first locking portion 26 in the outward direction (toward the first locking hole 18). The front end surface 28b of the protrusion 28 is formed in an inclined surface shape, and is configured to perform a guide function when the one end 22a of the connecting plug 22 is inserted into the first insertion hole 17. [Effects of this embodiment] The effects of the connection structure between the molding and the door mirror in this embodiment will be described below.

[0036] First, as shown in Fig. 3, one end 22a of the connecting plug 22 is inserted into the first insertion hole 17 of one end 22a of the molding 11 in the direction of the arrow. Then, the inclined front end surface 28b of the protrusion 28 of the connecting plug 22 slides against one edge of the first insertion hole 17 to guide the one end 22a into the first insertion hole 17, and the upper end surface 28a slides against the inner surface of the first insertion hole 17, i.e., the inner surface of the outer wall 13b of the base 13, to guide the one end 22a into the first insertion hole 17. At this time, the first locking portion 26 elastically deforms inward while the first tip portion 26b slides against the inner surface of one side wall of the first insertion hole 17, and moves inside while the entire first tip portion 26b side is accommodated in the first opening 24a.

[0037] 8(a) and 8(b), when the first engaging portion 26 reaches the position of the first engaging hole 18, the first tip portion 26b is elastically deformed outward by its own original elastic restoring force and enters the first engaging hole 18, and the inclined first tip surface 26c of the first engaging portion 26b is elastically engaged in line contact with the corner edge 18c of the first hole edge 18a. At this time, the claw portion 26d abuts against the lower end edge of the corner edge 18c of the first hole edge 18a to restrict further outward elastic deformation of the first tip portion 26b.

[0038] 4, with one end 22a of the connecting plug 22 locked and fixed in the first insertion hole 17 of the molding 11, the other end 22b of the connecting plug 22 is inserted into the second insertion hole 20 of the base member 19 of the door mirror 12. Then, in the same manner as the action of the first locking portion 26, the second locking portion 27 moves while being accommodated in the second opening 25a by elastically deforming the second tip portion 27b inward. Then, when the second locking portion 27 reaches the second locking hole 21, as shown in FIGS. 8(a) and (c), the second tip portion 27b elastically deforms outward by its own elastic restoring force and enters the second locking hole 21, and the inclined second tip surface 27c of the second tip portion 27b is elastically locked in line contact with the corner edge 21c of the first hole edge portion 21a. At this time, the claw portion 27d elastically contacts the corner edge 21c of the first hole edge portion 21a to restrict further elastic deformation outward of the second tip portion 27b.

[0039] As a result, one end 22 a of the molding 11 is firmly connected to the end 19 a of the base member 19 of the door mirror 12 via the connecting plug 22 .

[0040] In particular, in this embodiment, as described above, one end 22a and the other end 22b of the connecting plug 22 are inserted into the first insertion hole 17 of the molding 11 and the second insertion hole 20 of the base member 19, respectively, and the inclined first tip surface 26c of the first engagement portion 26 and the inclined second tip surface 27c of the second engagement portion 27 engage with the corner edge 18c of the first hole edge 18a of the corresponding first engagement hole 18 and the corner edge 21c of the first hole edge 21a of the corresponding second engagement hole 21.

[0041] Then, the molding 11 and the base member 19 are urged toward each other by the elastic force of the first locking portion 26 and the second locking portion 27 of the connecting plug 22, as shown by the arrows in Fig. 8(b) and (c). That is, as shown in Fig. 8(b), when the inclined first tip surface 26c of the first locking portion 26 elastically contacts the corner edge 18c of the first hole edge portion 18a of the first locking hole 18 from diagonally below, this elastic force becomes a force that urges the molding 11 toward the end portion 19a of the base member 19, as shown by the arrow in Fig. 8(b). On the other hand, at the same time, as shown in Fig. 8(c), when the inclined second tip surface 27c of the second locking portion 27 elastically contacts the corner edge 21c of the first hole edge portion 21a of the second locking hole 21 from diagonally below, this elastic force urges the base member 19 toward one end portion 22a of the molding 11, as shown by the arrow in Fig. 8(c).

[0042] In this way, when the inclined first tip surface 26c of the first engagement portion 26 and the inclined second tip surface 27c of the second engagement portion 27 elastically contact in a line contact state with the corner edges 18c, 21c of the hole edges 18a, 21a of the corresponding first and second engagement holes 18, 21, the elastic reaction forces in opposite radially outward directions of each engagement portion 26, 27 urge one end 11a of the molding 11 and the end 19a of the base member 19 of the door mirror 12 in a direction toward each other, i.e., in a direction of attracting each other.

[0043] As a result, as shown in Figures 2, 7 and 8(a), one end 22a of the molding 11 and the end 19a of the base member 19 of the door mirror 12 are in close contact with each other, sufficiently suppressing the occurrence of gaps and steps as in the prior art described in the above-mentioned publication, resulting in a sense of unity and a good appearance, and improving the appearance quality.

[0044] In addition, in this embodiment, since the first and second tip surfaces 26c, 27c of the first and second locking portions 26, 27 are formed in an inclined shape, it is not necessary to increase the relative dimensional accuracy of the distance T between the first hole edges 18a, 21a of the locking holes 18, 21 and the distance T1 (see FIG. 6(c)) between the tip surfaces 26c, 27c of the locking portions 26, 27. In other words, since the inclined tip surfaces 26c, 27c absorb the deviation between the distance T and the distance T1, it is not necessary to increase the relative dimensional accuracy. Therefore, the manufacturing operation is facilitated and the manufacturing cost is reduced. Second Embodiment FIG. 9(a) shows a second embodiment of the present invention, in which the structure of the second engaging portion 27 of the connecting plug 22 is the same as that of the first embodiment, but the structure of the first tip portion 26b of the first engaging portion 26 is modified.

[0045] That is, as shown in Figure 9 (c), the second engagement portion 27 of the connecting plug 22 has a second end surface 27c of the second end portion 27b formed into an inclined surface shape similar to the first embodiment, and this second end surface 27c is in elastic contact with the corner edge 21c of the first hole edge portion 21a of the second engagement hole 21.

[0046] On the other hand, as shown in Fig. 9(b), the first engaging portion 26 has a first tip surface 26c of the first tip portion 26b formed flat rather than inclined. That is, the first tip surface 26c is formed flat and substantially perpendicular to the outer surface of the first tip portion 26b. Therefore, when the first engaging portion 26 engages with the first engaging hole 18, the first tip surface 26c abuts in a surface contact state from the axial direction not against the corner edge 18c of the first hole edge portion 18a but against the flat surface 18d extending inward from the corner edge 18c.

[0047] Thus, in this embodiment, when the first locking portion 26 and the second locking portion 27 of the connecting plug 22 are locked into the corresponding first locking hole 18 and second locking hole 21, the first end surface 26c of the first locking portion 26 abuts in surface contact with the flat surface 18d of the first locking hole 18 in the axial direction, while the inclined second end surface 27c of the second locking portion 27 elastically locks into line contact with the corner edge 21c of the first hole edge portion 21a. In particular, the elastic force of the second locking portion 27 urges the base member 19 and the molding 11 in a direction toward each other.

[0048] Therefore, in this second embodiment, like the first embodiment, one end 22a of the molding 11 and the end 19a of the base member 19 of the door mirror 12 abut in a tight contact state, resulting in a good sense of unity and appearance, and improving the appearance quality.

[0049] In addition, since the second tip surface 27c of the second locking portion 27 is formed in an inclined shape, even if the first tip surface 26c of the first locking portion 26 is flat, there is no need to increase the relative dimensional accuracy of the distance T between the locking holes 18, 21 and the distance between each tip surface 26c, 27c of each locking portion 26, 27, as in the first embodiment. This makes the manufacturing process easier and reduces the manufacturing cost. Third Embodiment FIG. 10(a) shows a third embodiment of the present invention, in which the structure of the first tip portion 26b of the first engagement portion 26 of the connecting plug 22 is the same as in the second embodiment, but the structure of the second tip portion 27b of the second engagement portion 27 is modified.

[0050] That is, as shown in FIG. 10(b), the first engagement portion 26 has a first end surface 26c of the first end portion 26b formed flat as in the second embodiment, and this first end surface 26c abuts against a flat surface 18d extending inward from the corner edge 18c of the first hole edge portion 18a of the first engagement hole 18.

[0051] 10(c), the second engaging portion 27 has a second end surface 27c of the second end portion 27b that is not inclined but is formed flat like the first end surface 26c. Therefore, when the second engaging portion 27 is engaged with the second engaging hole 21, the second end surface 27c abuts in a surface contact state from the axial direction against the flat surface 21d, not against the corner edge 21c of the first hole edge portion 21a.

[0052] Thus, in this embodiment, when the first locking portion 26 and the second locking portion 27 of the connecting plug 22 are locked into the corresponding first locking hole 18 and second locking hole 21, the end faces 26c, 27c of each locking portion 26, 27 abut in a surface contact state against the flat faces 18d, 21c of each locking hole 18, 21, respectively, from the axial direction.

[0053] Therefore, unlike the first and second embodiments, the biasing force in the direction of bringing the base member 19 and the molding 11 closer to each other is not large, but if the relative dimensional accuracy of the distance T between the two locking holes 18, 21 and the distance between the tip faces 26c, 27c of the locking portions 26, 27 is relatively high, the one end 22a of the molding 11 and the end 19a of the base member 19 of the door mirror 12 can be brought into close contact with each other. As a result, the sense of unity and the appearance are improved, and the appearance quality is improved.

[0054] The present invention is not limited to the configurations of the above-described embodiments, and for example, the structure of the connecting plug 22 can be changed in accordance with the size and change of the cross-sectional shape of the first insertion hole 17 of the molding 11 and the second insertion hole 20 of the base member 19 of the door mirror 12. In addition, the structure of each of the locking portions 26, 27 can also be changed arbitrarily in accordance with the structural change of each of the locking holes 18, 21.
