Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a grommet into which the tip of a hood support rod for supporting an automobile hood in an open state is inserted and supported and fixed.

[Background Art] Conventionally, as shown in FIG. 1, in the hood of an automobile, the tip of a hood support rod 12 is pivotally attached to the lower surface of the hood 10 and locked. The grommet 11 is previously inserted and latched onto a grommet 11 attached to a support member 29 that is integrally provided at the upper end of the fender apron 13 and extends in the vertical direction of the vehicle body.

As shown in FIG. 2, the tip 24 of the hood support rod 12 is curved to prevent it from easily coming off the grommet 11 after being attached to the grommet 11. The grommet 11 into which the curved tip 24 is inserted includes a cylindrical portion provided with an insertion hole and a base portion extending concentrically with the cylindrical portion. And grommet 11
is made of a soft material such as rubber so that the tip 24 can be easily inserted. Therefore, the hood support rod 12 and the grommet 11
There was a problem in that rattling was likely to occur between the hood and the cylindrical portion of the hood, and the hood was easily damaged by the hood support load in the open state.

Therefore, it is conceivable to change the grommet 11 to a hard material, but if it is simply made of a hard material, it will be difficult to insert the curved tip 24 of the hood support rod 12. The inner diameter of the insertion hole of the part is larger than the outer diameter of the tip part 24. Therefore, the above-mentioned rattling still cannot be prevented.

Furthermore, since the hood 10 has a cantilevered structure, the load of the hood 10 is applied in a twisting manner from the engine room side toward the outside of the vehicle body.
It is difficult to provide sufficient support.

[Purpose of invention]

Taking the above facts into consideration, the present invention allows for easy insertion of the hood support rod, eliminates play between the grommet and the hood support rod, and ensures reliable transfer and support of the hood load to the vehicle body. The purpose of the present invention is to provide a grommet for an automobile hood support rod that can be used as a hood support rod.

[Summary of the idea]

The present invention is a hard material that is inserted and latched from inside the vehicle to a support member that extends in the vertical direction of the vehicle near the top of one of the fender aprons of the vehicle, and that supports and fixes the curved tip of the hood support rod. A grommet comprising: a rod insertion portion having an insertion hole into which the curved tip is tightly inserted; and a rod insertion portion provided with an insertion hole into which the curved tip portion is tightly inserted; an opening provided by enlarging the diameter of the insertion hole; and an opening that extends integrally in a direction intersecting the rod insertion portion and abuts against the vehicle inner side surface of the support member to support the rod insertion portion. and a pressure-receiving portion provided with at least a pressure-receiving area of a portion located on the lower side of the vehicle body relative to the opening portion than a pressure-receiving area of a portion located on the upper side of the vehicle body with respect to the opening portion. It is a feature.

According to the above structure, when the hood of the automobile is in the open state, the hood support rod is interposed between the hood and the grommet to maintain the hood in the open state.

When attaching the hood support to the grommet, the curved tip of the hood support must be inserted and latched into the insertion hole of the rod insertion part of the grommet.
With the grommet being supported and fixed to a support member extending in the vertical direction of the vehicle body near the top of the fender apron, the opening is provided by expanding the diameter of the insertion hole approximately in the vertical direction of the vehicle body, so that the curved tip The insertion operation of the part becomes easier.

Moreover, since the insertion hole is not enlarged in diameter except at the opening and the grommet is made of a hard material, no looseness occurs between the hood support rod and the insertion hole of the grommet. In addition, when the hood is open, that is, when the hood is supported by the hood support rod, the hood is cantilevered, and the load of the hood is transferred to the grommet via the hood support rod. The force acting on the grommet is the resultant force of the force pushing outward in the width direction of the vehicle body and the force pushing the vehicle body substantially downward. Here, in the present invention, the pressure receiving part, which extends integrally in a direction crossing the rod insertion part and comes into contact with the vehicle inner side surface of the support member, is located at least on the lower side of the vehicle body with respect to the opening. Since the pressure-receiving area of the hood is larger than the pressure-receiving area of the part located on the upper side of the vehicle body with respect to the opening, the load of the hood is supported by the lower part of this pressure-receiving part and is distributed near the top of the hood apron. distributed to Therefore, the load of the hood can be supported reliably.

Furthermore, even when the curved tip of the hood support rod is inserted, the load due to the insertion operation is similarly distributed to the vicinity of the upper part of the fender apron, thereby preventing damage to the grommet, especially the rod insertion portion. In addition to the load supporting effect of the hood, there is also the effect that the axial dimension of the rod insertion portion can be shortened.

[Explanation of Examples]

An embodiment of the present invention will be described below with reference to FIGS. 3 to 9. In explaining this embodiment, the same components as those in FIGS. 1 and 2 used to explain the conventional example are given the same numbers and the explanation thereof will be omitted.

As shown in FIG.
It consists of a rod insertion part 26, a support frame 30, a rod holding part 28, and a lip 27. The grommet 25 made of these elements is an integrally molded product made of hard synthetic resin.

The rod insertion part 26 is coaxial with the rod holding part 28, and both have a cylindrical shape. The rod holding part 28 has a cross-shaped slit 23 and is branched into four parts, so that it can also elastically deform and receive the curved tip part 24 of the hood support rod 12. Further, a recess 28 is provided on the outer periphery of the attachment portion of the rod holding portion 28 to the support frame 30, which will be described later.
A is formed for contacting an insertion hole formed in a support member 29 that is provided integrally with the upper end of the fender apron 13 and extends in the vehicle vertical direction.

The rod insertion part 26 and the rod holding part 28
The vicinity of the connecting portion is integrally fixed to the support frame 30. The support frame 30 has a substantially mountain-shaped shape and extends planarly in a direction perpendicular to the axial direction of the rod insertion portion 26, that is, in the vertical direction of the vehicle body. The dimension in the vehicle body width direction of the lower portion 30A located on the lower side of the vehicle body than the rod insertion portion 26 in the support frame 30 is the vehicle body width of the upper portion 30B located on the upper side of the vehicle body than the rod insertion portion 26 on the support frame 30. It is set sufficiently larger than the directional dimension. That is, when the grommet 25 is attached to the support member 29, the pressure receiving area for the load of the hood 10 is set to be sufficiently larger in the lower part 30A than in the upper part 30B.

Further, a lip 27 is provided at the lower end of the support frame 30 and is bent at right angles to the main plane of the support frame 30.

On the other hand, as shown in FIGS. 5 to 8, the rod insertion portion 26 of the grommet 25 is formed with a circular rod insertion hole 34 and a rod insertion hole opening 32 that communicates with the rod insertion hole 34. . The inner diameter of the rod insertion hole opening 32 is increased at a predetermined position on the circumference (in the vehicle body vertical direction in this embodiment) in accordance with the curved direction of the tip 24 of the hood support rod 12. Therefore, the tip 24 of the hood support rod 12 is inserted into the rod insertion hole 3 as shown in FIG.
4 can be inserted smoothly.

In addition, the inner diameter of the central portion of the rod insertion hole 34 (portion of the support frame 30) and the inner diameter of the rod insertion hole opening 32 in the longitudinal direction of the vehicle body are set to be slightly larger than the outer diameter of the tip portion 24, as shown in FIG. As shown in FIG. 9, the distal end portion 24 of the hood support rod 12 is prevented from wobbling after insertion.

The operation of this embodiment will be explained below.

When the grommet 25 has its rod presser part 28 inserted into the insertion hole of the support member 29, the rod presser part 28 is elastically deformed and the support member 2
It comes into close contact with the insertion hole 9.

In this state, the hood support rod 12 is attached to the grommet 25 by inserting the tip 24 of the hood support rod 12 into the rod insertion hole 34 of the rod insertion portion 26 of the grommet 25. Here, the rod insertion hole 34 is provided with a rod insertion hole opening 32 and is expanded in diameter in the vertical direction of the vehicle body.
The hood support rod 12 can be easily attached to the grommet 25 by inserting it in this diameter expanding direction. Further, since the diameter of the rod insertion hole opening 32 is not increased in the longitudinal direction of the vehicle body, no rattling occurs between the rod insertion hole opening 32 and the hood support rod 12.

Furthermore, in the open state of the hood 10, the hood 10
However, in this case, the load on the hood 10 is caused by the force in the direction of twisting from the engine room (not shown) toward the outside of the vehicle body and the own weight of the hood 10, and the load on the hood 10 is almost downward of the vehicle. A support frame 30 is formed on the grommet 25, and since this support frame 30 is in close contact with the support member 29, the lower part 30A Since the pressure receiving area of the upper part 30B is set larger than that of the upper part 30B, the load is applied to the lower part 30B of the support frame 30 in particular.
It can be transmitted to the support member 29 via A. Therefore, the grommet 25, especially the rod insertion portion 2
6 from being damaged, and the axial dimension of the rod insertion portion 26 can be shortened.

Also, since a lip 27 is provided at the lower end of the support frame 30, depending on the vehicle model, the lip 27 may
It is also possible to place the bottom surface of the hood 10 on a vehicle body component, and in this case, it functions as a rotation stopper for the grommet 25 in the installed state, and improves the function of dispersing the load of the hood 10 onto the vehicle body. can.

In the above embodiment, the rod insertion portion 26 is formed integrally with the support frame 30, but the present invention is not limited to this. For example, the support frame 36 may be formed of metal or the like, and the rod insertion portion 26 may be fixed thereto. good.

The present embodiment shown in FIGS. 3 to 9 is an embodiment that the applicant has judged to be the best; however, in the process of devising this embodiment, FIG. Even with the grommet 50 shown,
The load distribution effect is exerted to some extent. That is, in this structure, the support frame 20 has a substantially mountain-shaped shape like the support frame 30, but when comparing its lower part with the lower part 30A of the support frame 30, the support frame 20 actively receives pressure. Although it does not have the function of expanding the area, it does have a certain degree of load distribution function. Furthermore, since the rod insertion hole 22 of the rod insertion portion 16 has a uniform oval shape and is not constricted, the rattling prevention function is not sufficient. From the perspective that it was devised, it can be said to be of assistance in disclosing technical ideas.
