Description

  The present invention relates to a mirror base structure for supporting a side mirror with respect to a vehicle door.

  In a vehicle door mirror in which the base end portion of the base that supports the side mirror is fixed to the vehicle body door, in addition to a one-piece mirror base that exposes the base, conventionally, for example, a metal die-cast base and the base 2. Description of the Related Art A two-piece mirror base composed of a resin base cover is known (for example, Patent Document 1). In many such two-piece mirror bases, the base is inserted into the base cover through an opening formed in the base cover, and the two are coupled.

  Recently, a three-piece mirror base comprising a base and a base cover divided into two parts covering the base has also been adopted. In such a three-piece mirror base, the base is not inserted through the opening formed in the base cover, but the base is sandwiched in the vertical direction or the vehicle width direction by the two base covers so that the base is covered with the base cover. Many are housed inside. In this case, the two base covers usually have positioning pins and the like, and are configured to be independently positioned with respect to the base.

JP 2008-254552 A

  However, in the above-described three-piece mirror base, the two base covers are independently positioned with respect to the base, so that the positional relationship between one base cover and the base is shifted due to manufacturing variations of the base. There is a problem that the positional relationship between the two base covers is difficult to be determined. Such a problem is particularly noticeable when a metal die-cast base is used, which is difficult to obtain with high accuracy as compared with a resin-made one.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a mirror base structure for supporting a side mirror with respect to a vehicle door between parts due to manufacturing variations in a three-piece structure. An object of the present invention is to provide a technology that facilitates positioning between three parts while suppressing positional deviation.

  In order to achieve the above object, in the mirror base structure according to the present invention, one of the two resin base covers is positioned with respect to the base body, while the other base cover is aligned. Positioning is performed with respect to one base cover made of the same resin that is easy to perform.

  Specifically, the first invention is directed to a mirror base structure for supporting a side mirror with respect to a vehicle door.

Then, comprising a base body that is fixed to the door panel, cover a portion of the outer surface of the base body so as to sandwich the base body from above and below, an upper resin and the lower base cover, the upper SL upper and lower One of the side base covers includes a main positioning pin inserted through a first positioning hole formed in the base body in order to position the one base cover with respect to the base body. In order to suppress the rotation of one base cover relative to the base body, a sub-positioning pin to be inserted into a second positioning hole formed in the base body is formed, and the other base cover has the other base cover against one of the base cover above, for positioning rotatably around a vertical axis, fitted rotatably to the main positioning pin unite And positioning tube, for restricting the rotation relative to the base body of the base cover of those said other, a rotation restricting portion abutting on the base body, is formed,
The upper and lower base covers are inlay-fitted at the periphery of each other .

According to a second aspect, in the first aspect, the base body is made of aluminum die casting .

According to the mirror base structure according to the present invention, while positioning one of the base cover to the base body, the other base cover, positioned relative easy one base cover made of the same resin was position alignment Therefore, the other base cover can be accurately positioned with respect to the base body via the one base cover. Furthermore, for one of the base covers the other of the base cover, by rotatably positioned about the vertical axis, while allowing "play", by contacting the rotation restricting portion in the base body, the other side The rotation of the base cover can be restricted.

Therefore, in the mirror base structure, it is possible to facilitate the positioning between the three parts by suppressing the positional deviation between the parts due to manufacturing variations in the three-piece structure.

A resin upper panel 15 to be covered and a mirror base 3 for supporting the visor 11 with respect to the outer panel 31a of the vehicle are provided.

  In the following description, the mirror base 3 is described with reference to a state in which the mirror base 3 is attached to the outer panel 31a of the vehicle. The “rear side” refers to the “rear side in the vehicle front-rear direction” and the “front side”. Indicates the “front side in the vehicle longitudinal direction”.

  As shown in FIG. 2, the mirror base 3 for supporting the side mirror 1 with respect to the vehicle front door 31 includes the base body 5 fixed to the outer panel 31a and the base body 5 sandwiched from above and below. An upper base cover 7 and a lower base cover 9 that cover a part of the outer surface of the base body 5 are provided.

  The base body 5 is made of aluminum die casting, and protrudes to the right in the vehicle width direction from the mounting plate 17 attached to the outer panel 31a of the front door 31 and the upper end portion of the mounting plate 17 as shown in FIGS. In order to reinforce the support plate 19 and the support plate 19, four vertical ribs 21, 23, 25, 27 that connect the lower surface of the support plate 19 and the outer surface of the mounting plate 17, and four vertical ribs Are provided with a front horizontal rib 33 and a rear horizontal rib 35 that connect the front and rear vertical ribs 21 and 27 and the outer surface of the mounting plate 17 respectively.

  The mounting plate 17 is formed with two positioning pins 29 that extend leftward in the vehicle width direction and obliquely downward, and three substantially cylindrical mounting bosses 37 that also extend diagonally downward on the left side in the vehicle width direction. The mounting plate 17 is positioned with respect to the front door 31 by inserting two positioning pins 29 into two positioning holes (not shown) formed in the outer panel 31 a of the front door 31. At the same time, the three bolts are screwed into the screw holes 37a of the three mounting bosses 37 from the vehicle body side to be fixed to the outer panel 31a of the front door 31.

  As shown in FIG. 4, a concave portion 39 having a substantially circular cross section is formed in the central portion of the support plate 19, and a cylindrical portion 41 extending upward from the peripheral portion of the concave portion 39 is formed. By inserting the rotation shaft of the unit into the concave portion 39 and the cylindrical portion 41, the portion of the side mirror 1 above the mirror base 3 is supported. The cylindrical portion 41 is formed with two protrusions 43 protruding outward in the radial direction.

  The support plate 19 is formed with first, second and third engagement holes 45, 47 and 49 having a rectangular cross section around the cylindrical portion 41 in order from the front side. A first positioning hole 51 having a circular cross section is formed so as to be adjacent to the left side of the joint hole 49. Further, a second positioning hole 53 having an oval cross section is formed so as to face the first positioning hole 51 with the cylindrical portion 41 interposed therebetween.

  Both the front and rear horizontal ribs 33 and 35 are formed in a substantially triangular shape in plan view. Thus, the front horizontal rib 33 is formed with a fourth engagement hole 55 having a rectangular cross section at the front edge, and the front edge on the right side of the fourth engagement hole 55 in the vehicle width direction. A first engagement cutout 57 is formed by cutting out a substantially trapezoidal shape. On the other hand, the rear horizontal rib 35 is formed with a fifth engagement hole 59 having a rectangular cross section at the rear edge, and the rear edge is substantially outside the fifth engagement hole 59 in the vehicle width direction. A second engagement notch 61 cut out in a trapezoidal shape is formed.

Further, as shown in FIG. 5, the frontmost vertical rib 21 among the four vertical ribs is connected to the outer surface of the mounting plate 17 at substantially the same height as the front horizontal rib 33. A horizontal rib 63 is formed, and a front protrusion 65 extending in the vehicle width direction and protruding rearward is formed below the horizontal rib 63. On the other hand, of the four vertical ribs, the rearmost vertical rib 27 has a level substantially equal to that of the rear horizontal rib 35, and connects the vertical rib 27 and the vertical rib 25 on the one front side. A rib 67 is formed, and a rear ridge 69 extending in the vehicle width direction and projecting forward is formed below the horizontal rib 67.

  The upper base cover 7 is a thin resin molded product formed by using a mold, and as shown in FIGS. 6 and 7, a substantially elliptical shape that supports a portion of the side mirror 1 above the mirror base 3. Of the top wall 71, an inclined wall portion 73 that extends from the peripheral portion on the left side in the vehicle width direction of the top wall portion 71 toward the outer panel 31 a of the front door 31 while being gently inclined downward, and the vehicle of the top wall portion 71. It has an upper peripheral wall portion 75 extending downward from a peripheral portion on the right side in the width direction and a front edge portion and a rear edge portion (a peripheral portion excluding an edge portion on the outer panel 31a side) of the inclined wall portion 73. The lower end surface 75 a of the upper peripheral wall 75 constitutes a mating surface with the lower base cover 9.

  A circular insertion hole 77 is formed through the top wall 71 at the center thereof, and two notches 79 are formed at the peripheral edge of the insertion hole 77. The top wall 71 is formed with a first upper engagement portion 81 and a second upper engagement portion 83 that extend downward around the insertion hole 77, and the left side of the second upper engagement portion 83. A main positioning pin 85 extending downward is formed so as to be adjacent to each other, and a sub positioning pin 87 extending downward is formed so as to face the main positioning pin 85 with the insertion hole 77 interposed therebetween. Further, a third upper engagement portion 89 extending downward is formed in the vicinity of the front boundary between the top wall portion 71 and the inclined wall portion 73, while the rear side of the top wall portion 71 and the inclined wall portion 73. A fourth upper engaging portion 91 extending downward is formed in the vicinity of the boundary.

  These first to fourth upper engaging portions have different vertical lengths (the first upper engaging portion 81 and the second upper engaging portion 83 are short, the third upper engaging portion 89 and the fourth upper engaging portion are short). Although the engaging portion 91 is long), it basically has the same structure, and has a substantially wedge-shaped engaging claw at its tip.

Main positioning pins 85, the upper base cover 7, a projecting member extending downwardly for positioning with respect to the base body 5, are perpendicular intersecting substantially rectangular two plate-like members extending downward The cross section is formed like a cross. The sub-positioning pin 87 is also a protruding member that extends downward for positioning the upper base cover 7 with respect to the base body 5 and is formed in a cross-shaped cross section like the main positioning pin 85. Unlike the main positioning pin 85, the cross-shaped cross section is formed so as to increase upward from the central portion in the vertical direction.

  Further, four engaging protrusions 93 projecting inward from the inner peripheral surface of the upper peripheral wall 75 are formed at substantially equal intervals, and a space is formed between the upper peripheral wall 75 and the upper peripheral wall 75. Thus, three substantially L-shaped ribs 95 extending downward from the top wall portion 71 are formed so as to be positioned between the four engaging protrusions 93.

  On the other hand, the lower base cover 9 is a thin resin-molded product formed using a mold, like the upper base cover 7. As shown in FIGS. 8 and 9, a substantially semicircular resin plate is used. It is formed in a shape that is bent so as to be bent downward, and the entire peripheral edge portion excluding the edge portion on the outer panel 31a side constitutes a lower peripheral wall portion 97 that extends upward. Note that the upper end surface 97 a of the lower peripheral wall 97 constitutes a mating surface with the upper base cover 7.

The lower base cover 9 has a first lower engagement portion 99 that extends upward at the front end portion thereof, and a second lower engagement portion 101 that extends upward toward the center in the front-rear direction and the right side in the vehicle width direction. A third lower engaging portion 103 extending upward is formed at the rear end portion. These first to third lower engaging portions have basically the same structure as the first to fourth upper engaging portions, and have substantially wedge-shaped engaging claws at their tip portions.

Further, the lower base cover 9 has a positioning cylinder at a position corresponding to the main positioning pin 85 of the upper base cover 7 (between the second lower engaging portion 101 and the third lower engaging portion 103). 105 is formed. This positioning cylinder 105 is a cylindrical member extending upward for positioning the lower base cover 9 with respect to the upper base cover 7, and the lower side through the pedestal portion 107 formed of a thin plate member. A base cover 9 is provided. Since this pedestal portion 107 is formed in a U-shaped cross section, it can firmly support the positioning cylinder 105 provided at the tip thereof, and the cross section is constituted by a thin plate member. Therefore, the influence of the contraction is reduced, so that the occurrence of sink marks on the outer surface of the lower base cover 9 can be suppressed.

  Further, the lower base cover 9 has a rear side of the first lower engagement portion 99, more specifically, at a position corresponding to the right end of the front protrusion 65 of the base body 5 in the vehicle width direction. While a front rotation restricting portion 109 that abuts against the front ridge 65 is formed, on the front side of the third lower engagement portion 103, more specifically, a vehicle in the rear ridge 69 of the base body 5. A rear-side rotation restricting portion 111 that abuts against the rear-side protrusion 69 is formed at a position corresponding to the right end of the width direction.

  The front rotation restricting portion 109 extends from the upper surface of the lower base cover 9, extends in a direction substantially perpendicular to the front-rear direction, and has a substantially rectangular plate-like first front contact member 109 a and the upper surface of the lower base cover 9. The second and third front contact members 109b and 109c are substantially rectangular plate-shaped parallel to a direction orthogonal to the vehicle width direction. The first front contact member 109a and the second front contact member 109b have the same height, and the front end portion of the second front contact member 109b is connected to the central portion of the first front contact member 109a. The third front abutting member 109c is formed to be higher than the first and second front abutting members 109a and 109b, and the end of the first front abutting member 109a on the outer side in the vehicle width direction is formed. Is connected to the front end of the third front contact member 109c. Thus, in plan view, the first front contact member 109a and the second front contact member 109b are substantially T-shaped, and the first front contact member 109a and the third front contact member 109c are approximately. While forming an L shape, when viewed from the front-rear direction, the upper end of the first front contact member 109a and the portion of the third front contact member 109c that protrudes beyond the first front contact member 109a are substantially L-shaped. There is no.

  Similarly, the rear side rotation restricting portion 111 includes a first rear abutting member 111a having a substantially rectangular plate shape that extends upward from the upper surface of the lower base cover 9 and is parallel to a direction orthogonal to the front-rear direction. There are substantially rectangular plate-like second and third rear contact members 111b, 111c extending upward from the upper surface of the base cover 9 and parallel to a direction orthogonal to the vehicle width direction. The first rear contact member 111a and the second rear contact member 111b have the same height, and the rear end portion of the second rear contact member 111b is at the center of the first rear contact member 111a. On the other hand, the third rear abutting member 111c is formed to be higher than the first and second rear abutting members 111a and 111b, and is connected to the first rear abutting member 111a. The outer end in the vehicle width direction is connected to the rear end of the third rear contact member 111c. Thereby, the first rear contact member 111a and the second rear contact member 111b are substantially T-shaped in a plan view, and the first rear contact member 111a and the third rear contact member. 111c is substantially L-shaped, and when viewed from the front-rear direction, the upper end of the first rear contact member 111a and the portion of the third rear contact member 111c that protrudes from the first rear contact member 111a Are substantially L-shaped.

Further, the lower base cover 9 has a protruding wall 113 protruding upward and for suppressing the intrusion of wind into the base cover, in the vicinity of the inner side of the lower peripheral wall 97 and the lower peripheral wall 97. It is formed substantially in parallel. Then, the protrusion wall 113 fits into a space between the substantially L-shaped rib 95 formed on the upper base cover 7 and the upper peripheral wall portion 75, whereby the upper peripheral wall of the upper base cover 7. The upper base cover 7 and the lower base cover 9 are fitted in the inner periphery of each other at the peripheral edge portions.

  Furthermore, four engagement hooks (engagement portions) 115 that are hooked on the four engagement projections 93 formed on the upper base cover 7 are formed on the ridge wall 113. This engagement hook 115 is formed with an engagement hole 115 a at a portion between two notches 113 a formed in the ridge wall 113. Thus, since the engagement hook 115 is edge-cut from the rigid protrusion wall 113 by the two notches 113a, it can be bent and deformed using the elasticity of the resin.

  The base body 5, the upper base cover 7, and the lower base cover 9 configured as described above are assembled as follows.

  That is, in the upper base cover 7, as shown in FIG. 11, the main positioning pin 85 is inserted into the first positioning hole 51 having a circular cross section, and the sub positioning pin 87 is a second positioning hole 53 having an oval cross section. Is positioned with respect to the base body 5. In addition, the cylindrical portion 41 of the base body 5 is fitted in the insertion hole 77 of the upper base cover 7, and two protrusions 43 that protrude radially outward from the cylindrical portion 41 are formed on the peripheral edge of the insertion hole 77. Two notches 79 are fitted. Further, as shown in FIG. 10A, the engaging claw of the fourth upper engaging portion 91 of the upper base cover 7 is engaged with the fifth engaging hole 59 formed in the front horizontal rib 33 of the base body 5. 10B, the engaging claw of the second upper engaging portion 83 of the upper base cover 7 is engaged with the third engaging hole 49 formed in the support plate 19 of the base body 5. As shown in FIG. 10C, the engaging claw of the first upper engaging portion 81 of the upper base cover 7 is engaged with the first engaging hole 45 formed in the support plate 19 of the base body 5. 10D, the engagement claw of the third upper engagement portion 89 of the upper base cover 7 is formed in the fourth engagement hole formed in the front horizontal rib 33 of the base body 5. 55 is engaged.

  In this manner, the engagement claws of the four upper engagement portions of the upper base cover 7 engage with the four engagement holes of the base body 5 (more precisely, the hooks are caught by the peripheral portions of the four engagement holes). Thus, the upper base cover 7 is fixed to the base body 5 in the vertical direction. Since the main positioning pin 85 is inserted into the first positioning hole 51, the upper base cover 7 is also fixed to the base body 5 in the front-rear direction and the vehicle width direction.

  On the other hand, since the main positioning pin 85 having a cross-shaped cross section is inserted into the first positioning hole 51 having a circular cross section, the upper base cover 7 seems to rotate around the main positioning pin 85 with respect to the base body 5. However, when the upper base cover 7 tries to rotate around the main positioning pin 85, the auxiliary positioning pin 87 comes into contact with the long side portion of the second positioning hole 53 having an oval cross section. The base body 5 is also fixed in the direction of rotation around the vertical axis.

  In this way, the upper base cover 7 can be rotated around the main positioning pin 85 and the rotation is suppressed by the auxiliary positioning pin 87 inserted into the second positioning hole 53 having an oval cross section. Therefore, even when the base body 5 made of aluminum die casting, which is difficult to obtain with high accuracy as compared with the resin one, is used, the manufacturing variation of the base body 5 is absorbed and the upper base cover 7 is positioned and fixed to the base body 5. can do.

On the other hand, as shown in FIG. 11, the lower base cover 9 is positioned with respect to the upper base cover 7 by the main positioning pins 85 being fitted into the cylindrical holes 105 a of the positioning cylinder 105. Further, as shown in FIG. 12 (A), the engagement claw of the third lower engagement portion 103 of the lower base cover 9 has a second engagement notch formed in the rear horizontal rib 35 of the base body 5. The engaging claw of the second lower engaging portion 101 of the lower base cover 9 is formed on the support plate 19 of the base body 5 as shown in FIG. The engaging claw of the first lower engaging portion 99 of the lower base cover 9 is formed in the front horizontal rib 33 of the base body 5 as shown in FIG. The first engagement notch 57 is engaged. Further, the protrusion wall 113 is fitted into a space between the substantially L-shaped rib 95 formed on the upper base cover 7 and the upper peripheral wall portion 75, so that the upper base cover 7 and the lower base cover 9 Are inlay-fitted at the periphery of each other. In addition, the four engagement hooks 115 are hooked on the four engagement protrusions 93 formed on the upper base cover 7. Further, as shown in FIG. 13A, the front rotation restricting portion 109 abuts on the front protrusion 65, and as shown in FIG. 13B, the rear turn restricting portion 111 is rear projected. It abuts on the strip 69.

  As described above, the engaging claws of the three lower engaging portions of the lower base cover 9 are engaged with one engaging hole and two engaging cutout portions of the base main body 5, so that the lower base cover 9 is fixed to the base body 5 in the vertical direction unless it is intentionally removed. Further, since the main positioning pin 85 is fitted in the tube hole 105 a of the positioning tube 105, the lower base cover 9 is fixed to the upper base cover 7 in the front-rear direction and the vehicle width direction.

  On the other hand, since the main positioning pin 85 having a cross-shaped cross section is fitted in the cylindrical hole 105 a having a circular cross section, the lower base cover 9 may rotate around the main positioning pin 85 with respect to the upper base cover 7. It seems that the upper base cover 7 and the lower base cover 9 are inlay-fitted, so the lower base cover 9 is fixed to the upper base cover 7 in the rotational direction around the vertical axis. Has been.

  Of course, in the case of inlay fitting, the “play” is usually given in consideration of the ease of assembly. May shift around the vertical axis.

  Therefore, in the mirror base structure of the present embodiment, as described above, the front rotation restricting portion 109 is brought into contact with the front protrusion 65 and the rear turn restricting portion 111 is brought into contact with the rear protrusion 69. The structure to let you adopt is adopted. Thereby, as shown in FIG. 13A, the third front contact member 109c of the front rotation restricting portion 109 formed on the lower base cover 9 is in the vehicle width direction of the front protrusion 65 of the base body 5. While contacting the right end, as shown in FIG. 13B, the third rear contact member 111c of the rear rotation restricting portion 111 formed in the lower base cover 9 is By contacting the right end of the strip 69 in the vehicle width direction, the rotation of the lower base cover 9 with respect to the upper base cover 7 is restricted, and displacement is suppressed. 13A, the second front contact member 109b of the front rotation restricting portion 109 formed on the lower base cover 9 contacts the lower end of the front protrusion 65 of the base body 5. 13B, the second rear contact member 111b of the rear rotation restricting portion 111 formed on the lower base cover 9 is the lower end of the rear protrusion 69 of the base main body 5. As shown in FIG. It is possible to prevent the lower base cover 9 from being fitted too deeply into the upper base cover 7.

  In this way, while allowing the lower base cover 9 to rotate around the main positioning pin 85, the front rotation restricting portion 109 is brought into contact with the front protrusion 65 and the rear rotation restricting portion 111 is moved to the rear side. By adopting a configuration in which the positional deviation is suppressed by abutting against the protrusion 69, the lower base cover 9 is positioned with respect to the upper base cover 7 while allowing "play" in consideration of ease of assembly. be able to.

-Effect-
According to the present embodiment, since the main positioning pin 85 is formed on the upper base cover 7, the upper base cover 7 can be positioned with respect to the base body 5, while the lower base cover 9 is The positioning cylinder 105 is positioned with respect to the upper base cover 7 made of the same resin, which is easy to align, so that the lower base cover 9 is also accurate with respect to the base body 5 via the upper base cover 7. Can be positioned.

  Further, by positioning the lower base cover 9 with respect to the upper base cover 7 so as to be rotatable about the vertical axis, the rotation restricting portion that contacts the base body 5 while allowing “play” is provided. The positional deviation can be suppressed by restricting the rotation of the lower base cover 9 with respect to the upper base cover 7.

  Further, since the main positioning pin 85 is fitted into the positioning cylinder 105, the positioning reference between the three parts can be set at the same position, so that the relative position between these three parts can be easily determined.

  Further, when the rotation restricting portion comes into contact with the base body 5 in the rotation direction around the vertical axis, a positional deviation occurs in the rotation direction between the lower base cover 9 and the upper base cover 7. In addition, it is possible to prevent the lower base cover 9 from fitting too deeply into the upper base cover 7 by abutting in the vertical direction.

  In the above embodiment, the main positioning pin 85 is fitted to the positioning cylinder 105 and the positioning reference between the three parts is set to the same position. However, if the lower base cover 9 is positioned with respect to the upper base cover 7, Not limited to this, the lower base cover 9 may be positioned at a position different from the main positioning pin 85.

  In the above embodiment, the upper base cover 7 is positioned with respect to the base body 5, while the lower base cover 9 is positioned with respect to the upper base cover 7. While positioning with respect to the base body 5, the upper base cover 7 may be positioned with respect to the lower base cover 9.

  Further, in the above embodiment, the lower base cover is formed by bringing the front rotation restricting portion 109 into contact with the front protruding portion 65 and bringing the rear rotation restricting portion 111 into contact with the rear protruding portion 69. However, the front and rear rotation restricting portions 109 and 111 can also be used as follows. In other words, if it is known that a positional deviation has occurred at the prototype stage, the molds corresponding to the front and rear rotation restricting portions 109 and 111 are referred to based on the front and rear rotation restricting portions 109 and 111. It is possible to manufacture the position-adjusted lower base cover 9 without modifying other parts by scraping the part or conversely filling.
