[Industrial applications]

 The present invention relates to a mounting structure for automobile parts, and more particularly, to an improvement in a structure for mounting automobile parts such as a radiator tag on a vehicle body by a mounting tool such as a clip.

[0002]

[Prior art]

 Generally, automobile parts such as a radiator grill are attached to a vehicle body by a clip or a fitting such as a bolt and a nut. Here, a radiator grille as an automobile part is assembled between a bonnet and a bumper by elastically inserting a synthetic resin clip to a support portion such as a metal bracket on the vehicle body side. In addition, since the radiator grill of the type that is integrally assembled under the bonnet is subject to frequent vibrations and shocks as the bonnet is opened and closed, the radiator grill will be installed more firmly on the vehicle body than the normal radiator grill. There is a need. However, clips used for radiator grilles usually have a weak attachment force to the vehicle body against such frequent vibrations and shocks, and synthetic resin clips have friction between metal support parts. As a result, the contact part may be worn away and play may be loosened, and it is necessary to improve the mounting force. Therefore, in order to improve the attachment force to the vehicle body, a configuration has been proposed in which the radiator grill is fastened and fixed to the vehicle body by bolts and nuts instead of clips. As such a configuration, the configurations shown in FIGS. 6 and 7 can be considered.

FIG. 6 is a sectional view showing a mounting structure of a conventional undercut seat type automobile part. Further, FIG. 7 is a cross-sectional view showing a mounting structure of a conventional stud bolt type automobile part.

In FIG. 6, the grill main body 51 of the radiator grill protrudes from the rear surface of the grill main body 51 to the vehicle body side in order to improve the design effect when viewed from the outside of the vehicle when it is mounted on the vehicle body of the automobile. A large number of tubular undercut portions 52 are provided on the entire surface of the grill main body 51. L-shaped plate-like support pieces 53 that open laterally are integrally formed at predetermined positions such as upper and lower end portions on both left and right sides of the grill main body 51, and bolts 54 are supported from the inside of the support pieces 53. The shank 53 is inserted into the insertion hole 53a of the piece 53 so that the shaft portion projects toward the vehicle body. The support piece 53 and the bolt 54 constitute an attachment tool for attaching the radiator grill to the vehicle body. Then, the shaft portion of the bolt 54 attached to the support piece 53 is inserted into the insertion hole (not shown) of the support portion such as a bracket fixed to the vehicle body side, and the nut (not shown) is screwed from the tip of the bolt 54. When fitted together, the radiator grill is assembled and held on the vehicle body.

On the other hand, in FIG. 7, cylindrical support tubes 62 projecting toward the vehicle body are integrally formed at predetermined positions such as upper and lower end portions on both left and right sides of the grill body 61, and the opening of the support tube 62 on the vehicle body side is formed. The insertion portion 64 on the base end side of the stud bolt 63 is inserted in the. A large number of irregularities are formed on the peripheral surface of the insertion portion 64 of the stud 63 by knurling or the like to increase the frictional force between the stud 63 and the inner surface of the support cylinder 62 to support the stud 63. It is fixed to the cylinder 62 so that it cannot rotate. Further, the flange portion 66 disposed between the insertion portion 64 of the stud bolt 63 and the shaft portion 65 on the tip side is brought into contact with and supported by the tip surface of the support tube 62. The support cylinder 62 and the studs 63 form an attachment for attaching the radiator grill to the vehicle body. Then, the shaft portion 65 of the stud bolt 63 attached to the support cylinder 62 is inserted into the insertion hole (not shown) of the support portion such as a bracket fixed to the vehicle body, and the shaft portion 65 of the stud bolt 63 is inserted from the tip of the shaft portion 65. By screwing a nut (not shown), the radiator grill is assembled and held on the vehicle body.

[0006]

[Problems to be solved by the device]

 The conventional mounting structure for automobile parts is configured as described above. In the conventional example of the undercut seat type shown in FIG. 6, the mounting tools are usually the left and right upper and lower end portions of the grill body 51 and the central both end portions thereof. Since it is provided at six positions, the undercut portion 52 exists near the support piece 53 of the fixture, particularly near the open side. Therefore, when the grill body 51 is subjected to injection molding during injection molding, the undercut portion 52 makes it difficult to remove the portion corresponding to the space between the undercut portion 52 and the supporting piece 53. there is a possibility. Further, in order to avoid such an inconvenience, a slide portion is provided on the grill main body 51 or a special molding cycle is required, which may increase the manufacturing cost.

In the conventional example of the stud bolt type of FIG. 7, when the nut is tightened to the shaft portion 65 of the stud bolt 63 of the fixture, the rotational force of the nut is inserted through the shaft portion 65. 4 is transmitted to the inner peripheral surface of the support cylinder 62 and the peripheral surface of the insertion portion 64 of the implant bolt 63, the implant bolt 63 rotates against the holding force due to the frictional resistance, and the nut idles. Tightening may not be possible. Further, if the axis of the stud bolt 63 does not coincide with the axis of the support cylinder 62 due to variations in the work of inserting the insertion portion 64 of the stud bolt 63 into the support tube 62, The shaft portion 65 of the stud bolt 63 may not be able to be inserted into the insertion hole of the support portion such as a bracket of the vehicle body, the nut may not be tightened, and the assembly may be defective. is there.

Therefore, the present invention provides a mounting structure for automobile parts, which improves the mounting force of the automobile parts to the vehicle body, does not require a special manufacturing process, and is easy and reliable to assemble. Is an issue.

[0009]

FIG. 5 is a sectional view showing a state in which a radiator grill is assembled to a vehicle body using the mounting structure for automobile parts according to an embodiment of the present invention.

As shown in FIGS. 1 and 5, in this embodiment, a radiator grille 10 of a type that is integrally assembled as a vehicle component under a hood 1 of an automobile and is opened and closed together with the bonnet 1. Is illustrated. 2 and 4, the grill body 11 of the radiator grill 10 has a large number of undercut portions 12 recessed rearward (on the side of the hood 1) in order to improve its design effect. Along with the upper and lower end portions of the grill main body 11 and the inner upper and lower end portions of the center, mounting portions 13 are arranged respectively. In this embodiment, each mounting portion 13 has an undercut shape that is recessed rearward, and a mounting hole 14 is formed in the bottom of each mounting portion 13. The attachment hole 14 is formed in a substantially convex shape in plan view from the insertion portion 14a arranged on the lower side and the holding portion 14b which is narrower than the insertion portion 14a arranged on the upper side and connected to the insertion portion 14a. . Around the mounting hole 14 of the mounting portion 13, four locking bases 15 as locking means are integrally formed on a circle centered on the mounting hole 14. Each of the locking bases 15 has a plane quadrant shape and protrudes rearward from the mounting portion 13, and a substantially cross-shaped clearance 16 is provided between the four locking bases 15. The mounting holes 14 are arranged at the intersections of the gaps 16 between the holes 15.

On the other hand, the pedestal 21 is formed of a synthetic resin in the shape of a block in the shape of a planar cross-section corresponding to the gap 16 between the locking bases 15, and can be fitted into the gap 16 between the locking bases 15. Further, an insertion piece 22 made of synthetic resin is integrally formed at a substantially central position on the front surface (side of the grill body 11) of the pedestal 21. The insertion piece 22 has a flat T-shaped plate shape, and the hooking portion 22a at the front end thereof is narrower than the insertion portion 14a of the mounting hole 14 and wider than the holding portion 14b. The neck portion 22b at the end is narrower than the holding portion 14b of the mounting hole 14. A head portion 23a of a bolt 23 is integrally embedded in the pedestal 21 at the time of molding, and a shaft portion 23b of the bolt 23 projects rearward from a substantially central position on the rear surface of the pedestal 21. The pedestal 21, the insertion piece 22, and the bolt 23 constitute the fixture 20 of this embodiment.

The stepped portion between the insertion portion 14 a and the holding portion 14 b of the mounting hole 14 is, for example, a tapered guide surface 14 c that expands rearward, and the pedestal 21 is fitted into the gap 16 of the locking base 15. When fitted, the tip of the hooking portion 22a of the insertion piece 22 is configured to abut and abut the guide surface 14c of the mounting hole 14. A support portion 31 is integrally provided at a lower position of the bonnet 1 facing the attachment portion 13 of the grill body 11, and the shaft portion 23b of the bolt 23 of the attachment tool 20 can be inserted into each support portion 31. An insertion hole 32 is provided. When the attachment 20 is attached to the attachment 13 and the grill main body 11 is attached to the support 31 below the bonnet 1, the pedestal 21 of the attachment 20 abuts the support 31 and the shaft of the bolt 23. The portion 23b passes through the insertion hole 32 of the support portion 31 and projects to the back side of the support portion 31. A nut 33 is screwed into the tip of the shaft portion 23b of the bolt 23 inserted into the insertion hole 32 of the support portion 31 via a washer (not shown).

Next, an assembling work of the radiator grille 10 using the mounting structure for automobile parts of the present embodiment configured as described above will be described.

First, in order to attach the fixture 20 to the grill body 11 of the radiator grill 10, the fixture 20 is made to face each attachment portion 13 of the grill body 11, and the pedestal 21 is fitted into the gap 16 between the locking bases 15. To meet. At this time, the tip of the hooking portion 22a of the insertion piece 22 protruding from approximately the center of the front surface of the pedestal 21 guides the upper edge of the insertion portion 14a of the attachment hole 14 located at the intersection of the gap 16 of the locking base 15. It faces the surface 14c (insertion position). From this state, when the pedestal 21 is slidably guided along the inner side surface of the locking base 15 and the attachment tool 20 is moved toward the attachment portion 13, the hooking portion 22a of the insertion piece 22 is released. It abuts the guide surface 14c of the mounting hole 14 and slides on the guide surface 14c, and due to its elasticity, it is bent downward along the guide surface 14c and enters the insertion portion 14a. When the insertion piece 22 of the attachment 20 is further advanced into the insertion portion 14a of the attachment hole 14 of the attachment portion 13, the hook portion 22a of the insertion piece 22 passes through the insertion portion 14a of the attachment hole 14. When the neck portion 22b of the attachment piece 22 is located in the insertion portion 14a of the attachment hole 14, the hook portion 22a of the attachment piece 22 is released from the engagement with the guide surface 14c of the attachment hole 14 and its elasticity is reduced. The shape is restored upward by. As a result, the hooking portion 22a of the insertion piece 22 faces the holding portion 14b of the mounting hole 14, and the step surface between the hooking portion 22a and the neck 22b holds the mounting hole 14 on the front surface of the mounting portion. The left and right edges of the portion 14b are supported in contact with each other (holding position). At this time, the neck portion 22b of the insertion piece 22 is narrower than not only the insertion portion 14a of the attachment hole 14 but also the holding portion 14b, so that the neck portion 22b of the insertion piece 22 is located at the periphery of the attachment hole 14 of the attachment portion 13. Does not interfere with the upward recovery of the shape of the hook portion 22a. As a result, the hook portion 22a of the insertion piece 22 is irremovably hooked to the edge portion of the attachment hole 14 of the attachment portion 13 on the side of the holding portion 14b, and the pedestal 21 and the bolt 23 are also irremovably attached to the grill body 11. Retained. In this state, the shaft portion 23b of the bolt 23 of the mounting tool 20 extends rearward from the mounting portion 13 of the grill body 11.

Next, in order to mount the grill main body 11 with the mounting fixture 20 mounted on the supporting portion 31 below the bonnet 1, the grill main body 11 is moved horizontally toward the supporting portion 31 and brought closer to the mounting portion 20. The shaft portion 23b of the bolt 23 is inserted into the insertion hole 32 of the support portion 31, and the pedestal 21 is brought into contact with and supported by the front surface of the support portion 31. Then, the nut 33 is screwed and fastened to the shaft portion 23b of the bolt 23 of the fixture 20 protruding from the insertion hole 32 of the support portion 31 via the washer, whereby the grill main body 11 is fixed to the fixture 20 and the attachment portion 13. As shown in FIG. 1 and FIG. 5, it is integrally assembled and held at a predetermined position below the bonnet 1 via. At this time, since the grill main body 11 is assembled and held on the support portion 31 by the mounting tool 20, the upper and lower end portions on both the left and right sides and the upper and lower end portions in the center are assembled and held in the support portion 31. Therefore, it is not easily detached from the support portion 31 due to vibration or the like when the vehicle is running.

In order to remove the grill main body 11 assembled to the support portion 31 in this way from the support portion 31, the hook portion 22a of the insertion piece 22 of the fixture 20 is moved downward by using a tool such as a screwdriver. Elastically deformed and moved from the holding portion 14b of the mounting hole 14 of the mounting portion 13 to the insertion portion 14a. In this state, when the grill main body 11 is pulled slightly to the front side, the insertion piece 22 slightly enters the insertion portion 14a of the attachment hole 14. Therefore, even if the downward pressing of the insertion piece 22 by a tool such as a driver is released, the hook portion 22a of the insertion piece 22 contacts the guide surface 14c of the attachment hole 14 of the attachment portion 13 and The elastic force of the sliding force slides on the guide surface 14c of the mounting hole 14 and urges the grill main body 11 in the direction to separate it. Therefore, the insertion piece 22 of each attachment 20 can be easily removed from the corresponding attachment hole 14 of the attachment portion 13, and the grill body 11 can be removed from the support portion 31. In this state, the fixture 20 is attached and held by the support portion 31.

In order to attach the grill body 11 thus removed to the support portion 31 again, the grill body 11 is supported by the support portion 31 so that the pedestal 21 of the fixture 20 faces the gap 16 between the locking bases 15. By moving the base 21 horizontally toward the pedestal 21 and fitting the pedestal 21 into the gap 16 between the locking bases 15, the insertion piece 22 of the attachment 20 is inserted into the insertion hole 14 of the attachment 13 in the same manner as described above. After being inserted into 14a, it is hooked on the holding portion 14b of the mounting hole 14. As a result, the grill main body 11 is reassembled and held by the support portion 31 below the bonnet 1 via the attachment tool 20 and the attachment portion 13.

As described above, the mounting structure for automobile parts according to the above-described embodiment is recessed rearward (on the side of the hood 1) inside the upper and lower end portions and the central upper and lower end portions of the grill body 11 of the radiator grill 10. An undercut-shaped mounting portion 13 is provided, and a mounting hole 14 having a substantially convex shape in a plane is formed in the bottom portion of the mounting portion 13 by an insertion portion 14a and a holding portion 14b formed narrower than the insertion portion 14a. At the same time, a stepped portion between the insertion portion 14a of the mounting hole 14 and the holding portion 14b is used as a tapered guide surface 14c that expands rearward, and a flat quadrant is formed around the mounting hole 14 of the mounting portion 13. Four locking bases 15 projecting rearward are integrally formed, a substantially cross-shaped clearance 16 is provided between the four locking bases 15, and the mounting hole 14 is arranged at the intersection of the clearances 16. , Base 21 made of synthetic resin Is formed in a planar cross shape block shape corresponding to the gap 16 between the locking bases 15 so that it can fit in the gap 16 between the locking bases 15, and is wider than the insertion portion 14 a of the mounting hole 14. The hooking portion 22a that is narrower than the holding portion 14b and the neck portion 22b of the mounting hole 14 that is narrower than the holding portion 14b forms a flat T-shaped plate-like insertion piece 22 on the front surface of the pedestal 21. When integrally formed on the grill body 11 side and the pedestal 21 is fitted into the gap 16 between the locking bases 15, the tip of the hooking portion 22a on the tip side of the insertion piece 22 is attached to the mounting portion 22a. The head 23a of the bolt 23 is integrally embedded in the pedestal 21 at the time of molding so that the shaft portion 23b of the bolt 23 can be abutted and guided by the guide surface 14c of the hole 14. The pedestal 21 is projected rearward from the rear surface. .

Therefore, in the above embodiment, the pedestal 21 is fitted into the gap 16 between the locking bases 15 of the grill body 11, and the tip of the hooking portion 22a of the insertion piece 22 is guided to the guide surface 14c of the mounting hole 14. By abutting against the guide surface 14c and slidingly guiding the guide surface 14c, the elasticity of the insertion piece 22 causes the insertion piece 22 to bend downward along the guide surface 14c of the mounting hole 14 and enter the insertion portion 14a. Then, when the hooking portion 22a of the insertion piece 22 passes through the insertion portion 14a of the attachment hole 14 and the neck portion 22b of the insertion piece 22 is positioned at the insertion portion 14a of the attachment hole 14, the insertion piece 22 The engagement portion 22a is released from the engagement with the guide surface 14c of the mounting hole 14, and the insertion piece 22 returns to the shape upward due to its elasticity, so that the step surface between the engagement portion 22a and the neck portion 22b is formed. The attachment hole 14 is supported by abutting against the left and right edges of the holding portion 14b. As a result, the insertion piece 22 is irremovably hooked in the attachment hole 14 of the attachment portion 13, and the attachment tool including the pedestal 21, the insertion piece 22 and the bolt 23 is irremovably attached and held to the grill body 11. It In this state, the shaft portion 23b of the bolt 23 of the fixture 20 is inserted into the insertion hole 32 of the support portion 31 on the side of the hood 1 of the automobile, and the nut 33 is screwed from the tip thereof, whereby the radiator grille 10 is attached. It is attached to the support portion 31 via the tool 20. At this time, since the fastening force of the bolts 23 and the nuts 33 is strong, the mounting force of the radiator tag grill 10 by the mounting tool 20 is not reduced or the mounting rattling occurs even when the vehicle travels. Absent. As a result, the radiator grille 10 can be stably assembled and held on the vehicle body, and the product quality can be improved.

Further, since the bolts 23 of the fixture 20 are made of metal, like the conventional synthetic resin clips, they come into contact with the peripheral edge of the insertion hole 32 of the metallic support portion 31 on the bonnet 1 side. There is no risk of wear, backlash, and reduction in mounting force. When the grill body 11 is injection-molded during injection molding, the mounting portion 13 has an undercut shape recessed in the same direction as the undercut portion 12, and the locking base 15 also projects in the same direction. Since the gap 16 is provided between them, they do not hinder the die removal of the grill body 11. As a result, unlike the undercut seat type conventional example of FIG. 6, there is no difficulty in removing the die due to the structure for the mounting tool, so that the grill body 11 is provided with a slide portion, or a special case is used. No molding cycle is required and manufacturing costs are not increased. Further, when the nut 33 is tightened on the shaft portion 23b of the bolt 23 of the fixture 20 as in the conventional stud type of FIG. 7, the rotational force is transmitted to the pedestal 21 via the shaft portion 23a. Even when the pedestal 21 is fitted, the pedestal 21 is fitted in the gap 16 between the locking bases 15 and is non-rotatably supported by the locking bases 15. Therefore, the nut 33 does not run idle and cannot be tightened. .

By the way, the mounting portion 13 of the above embodiment has an undercut shape that is recessed in the same direction as the undercut portion 12, and a mounting hole 14 is provided at the bottom of the mounting portion 13 that extends in a substantially vertical direction. However, the present invention is not limited to this, and the attachment 20 can be attached and the grill main body 11 can be attached to the grill main body 11 via the attachment 20. It suffices that it can be assembled at a predetermined position of the vehicle body, and for example, the mounting hole 14 may be provided on the horizontal surface of the grill body 11 and the mounting tool 20 may be mounted in the vertical direction. In this case, the grill main body 11 to which the attachment 20 is attached is assembled and held on the support portion 31 by vertically moving the bolt 23 of the attachment 20 and screwing and tightening the nut.

Further, the locking base 15 of the above embodiment is formed in a quadrant shape, and the shape of the pedestal 21 is formed in a cross block shape corresponding to the gap 16 between the locking bases 15. In addition to the quadrant shape, the shape of 15 may be any shape as long as it engages with the pedestal 21 and functions to restrict the rotation of the pedestal 21 and does not hinder the die removal when the grill body 11 is molded. The shape of the pedestal 21 can be changed to a shape other than the cross block according to this. For example, the locking base 15 is formed in a block shape having a polygonal concave portion such as a flat triangular shape or a square shape in the center, and the pedestal 21 is formed in a block shape having a planar polygonal diameter corresponding to the concave portion. It is also possible to make it non-rotatable by the locking base 15. Alternatively, the locking base 15 may be separately mounted without being integrally formed with the mounting portion 13.

Further, as a configuration in which the insertion piece 22 can be moved between an insertion position where it can be inserted into the attachment hole 14 and a holding position which is displaced after insertion and cannot be removed from the attachment hole 14, In addition to those shown in the above-mentioned embodiment, for example, a guide surface is provided at the tip of the hooking portion 22a of the insertion piece 22 so as to be guided to the upper edge of the insertion portion 14a of the mounting hole 14, or the insertion piece. Other configurations may be adopted, such as a pair of upper and lower 22 and a configuration in which either the left portion or the right portion of the retaining portion 22a of the insertion piece 22 is retained by the holding portion 14b of the mounting hole 14. it can. Further, in a state where the insertion piece 22 is inserted into the attachment hole 14, elasticity of the insertion piece 22 in the length direction is imparted, and the hooking portion 22 a of the insertion piece 22 is attached to the attachment hole 14 of the attachment portion 13. The left and right side edges of the holding portion 14b may be elastically pressed. In this case, when the radiator grill 10 is removed, the hooking portion 22a of the insertion piece 22 can be lengthened simply by pushing down the hooking portion 22a of the insertion piece 22 so as to face the insertion portion 14a of the mounting hole 14. Since the elastic force in the vertical direction automatically enters the mounting hole 14, the radiator grill 10 can be removed more easily. In addition to the radiator grille 10 of the above embodiment, the present invention can be applied to other automobile parts as long as it is an automobile part that needs to be attached to the vehicle body by a combination of bolts and nuts. Further, the fixture of the present invention can be arranged in a total of four places on the left and right upper and lower ends of the grill main body 11, so that the number and the arrangement position thereof can be changed.
