Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a bumper bar mounting structure for an opening / closing lid.

<Prior Art> Conventionally, as a bumper bar for receiving and absorbing an impact generated when the opening / closing lid is closed, as shown in FIG. 4, a sheet-shaped bumper bar 1 is simply bonded to the lid 2 with an adhesive, or There is widely known a bumper bar 6 in which a hole 4 is made in a lid 3 as shown in FIG. 5, and a bulged portion 5 having a constant height is formed on both front and back sides after being inserted therein.

<Problems to be Solved by the Invention> However, in such a conventional technique,
When attaching the bumper bar 1 with adhesive as shown in the figure,
There is a possibility that the bumper bar 1 may be displaced with respect to the lid 2 before the adhesive is solidified, and provisional measures such as temporary fixing must be taken to prevent this, which is disadvantageous in terms of attachment.

Also, in the case of the bumper bar 6 as shown in FIG. 5, it is difficult to perform the work for inserting the bumper bar 6 into the hole 4, and similarly, it cannot be said that it is preferable in terms of mountability. Moreover, in the case of this bumper bar 6, since rubber material having a very high hardness cannot be adopted in consideration of the insertion into the hole 4, the height h must be increased in order to obtain a certain cushioning effect, and the closure Even when the lid is open, the lid 3 is slightly raised.

The present invention was made by paying attention to such a conventional technique, and it has a good mounting property and a bumper bar mounting structure of an opening / closing lid that can obtain a sufficient cushioning effect without increasing the height size. Is intended to be provided.

<Means for Solving the Problem> In order to achieve the above-mentioned object, the opening / closing lid bumper bar mounting structure according to the present invention has an opening / closing lid in which a front side member and a back side member are assembled with each other to form a hollow portion inside. In the bumper bar mounting structure, a notch is formed in the end of the back member, a recess for inserting the end is formed in the bumper bar, and the recess is inserted into the notch when the end is inserted. A convex portion is formed, and a support portion having a shape projecting into the hollow portion is integrally formed on the front side member, and the support portion abuts and supports the bumper bar from the hollow portion side, and an impact force on the hollow portion side that is applied to the bumper bar. Is transmitted to the front side member via the support portion.

<Operation> The bumper bar can be attached to the lid just by inserting it, so it is easy to attach. In addition, since the convex portion formed in the concave portion of the bumper bar engages in the notch of the lid at the time of insertion, the bumper bar can be securely attached to the lid without misalignment or separation.

Also, since the bumper bar is supported by the support part that is integrally formed with the front side member after mounting, it is possible to reliably receive the impact force applied to the bumper bar without setting the height (thickness) of the bumper bar itself too large. It is possible to obtain a sufficient buffering effect.

<Embodiment> A preferred embodiment of the present invention will be described below with reference to FIGS.

A parcel storage device 7 is arranged on a rear parcel shelf 9 located behind a rear seat 8 of the automobile. The parcel storage device 7 is provided with a lid 11 that pivots upward to pivot about a pivot shaft 10 on one end side. This lid 11 is a front side member assembled to each other with a plurality of screws 12.
It is composed of 13 and a back member 14, and a hollow portion 15 is formed inside. Further, a skin 16 is attached to the surface of the front side member 13 in order to prevent appearance and improve the touch.

And in the left and right corners of the back member 14 of the lid 11
A bumper bar 17 made of NBR (Shower hardness 60) is attached to each. The bumper bar 17 comes into contact with a projection 20 formed on a frame 19 forming an upper opening of the storage box 18 when closed, and can reduce (absorb) a shock when closing the lid 11.

The bumper bar 17 is attached to the end 21 of the back member 14 corresponding to the left and right corners of the lid 11, and the end 21 is provided with a notch 22 having a substantially keyhole shape. The introduction portion 22a of the notch 22 has a convex portion 24, which will be described later.
The end 21 side is slightly open so that it can be easily received. The bumper bar 17 is provided with a recess 23 having a size corresponding to the thickness d of the end 21 and having a predetermined depth.
Moreover, in this concave portion 23, a convex portion 24 having a shape corresponding to the notch 22 is formed.
Are formed.

On the other hand, on the back side surface of the front member 13, a columnar support portion 25 projecting into the hollow portion 15 is integrally formed.

Next, how to attach the bumper bar 17 will be described. First, to the end member 21 of the back side member 14 before being assembled to the front side member 13,
The recess 23 of the bumper bar 17 is inserted, and the protrusion 24 in the recess 23 is engaged in the notch 22. Since the notch 22 and the convex portion 24 both have a substantially keyhole shape as described above, the engagement of the notch 22 and the convex portion 24 positions the bumper bar 17 with respect to the end portion 21 and prevents the bumper bar 17 from coming off. Are done at the same time.
Then, the back side member 14 to which the bumper bar 17 is attached is attached to the front side member 13 with screws 12. Then, when the back side member 14 is assembled to the front side member 13, the bumper bar 17 comes into contact with the tip of the support portion 25 and is supported by the support portion 25. Therefore, the impact force applied to the bumper bar 17 when colliding with the protrusion 20 can be transmitted to the front side member 13 via the support portion 25. Further, when the back side member 14 is assembled, the end 16a of the outer skin 16 is sandwiched between the end portion 26 of the front side member 13 and the tip of the bumper bar 17 so that the end treatment of the outer skin 16 can be performed at the same time.

In the above description, the columnar support portion 25 is purposely formed so as to project on the front side member 15. However, depending on the lid 11, the front side member 15 may be processed due to the end treatment (graining) of the skin 16.
There is a case where the end portion 26 of the above is partially projected toward the hollow portion 15 side, and thus the projected portion can be freely used as the “support portion”. Furthermore, the shape and size of the bumper bar 17 can be arbitrarily set to cover the internal structure of both corners of the front member 13, which is also advantageous in appearance.

<Effects of the Invention> The structure of the opening / closing lid for mounting the bumper bar according to the present invention is as described above. The bumper bar can be mounted on the lid only by inserting it, so that the mounting property is good. Moreover, since the convex portion formed in the concave portion of the bumper bar is inserted into the notch when the plug is inserted, there is no positional displacement or separation of the bumper bar with respect to the lid, and a reliable mounting state can be obtained.

Also, since the bumper bar is supported by the support part that is integrally formed with the front side member after mounting, it is possible to reliably receive the impact force applied to the bumper bar without setting the height (thickness) of the bumper bar itself too large. It is possible to obtain a sufficient buffering effect.

Further, by arbitrarily setting the shape and size of the bumper bar, the internal structure of the front member can be covered, which is also advantageous in appearance.
