Description

[Detailed Description of the Invention] This invention particularly relates to an improvement in the fixing structure between a resin bumper face and a metal bumper reinforcement.

Conventionally, as this type of fixing structure, the one shown in FIG. 1 is known.

This is a metal bumper face 1 that has holes 1c for inserting stepped bolts B in the upper and lower ends 1a and 1b of a resin-molded bumper face 1, respectively, and is attached to the front or rear of the vehicle body via a bumper stay (not shown). The upper and lower ends 2a of the bumper reinforcement 2,
A hole 2c for inserting the stepped bolt B is opened in 2b so as to be concentric with the hole 1c, and these holes 1
The bumper face 1 is fixed to the bumper reinforcement 2 by inserting and tightening the stepped bolts B into holes c and 2c.
-Refer to Publication No. 51639).

However, such a conventional fixing structure for the bumper face 1 has a problem in that workability is poor because it is necessary to tighten the stepped bolts B one by one.

As a means to solve the problems in the conventional fixing structure of the bumper face 1, as shown in FIG. , bumper face 1
It is also possible to simplify the workability of fixing the
When a collision load F is applied to the bumper, which is a vehicle collision buffer member, the bumper face 1 slides rearward and a shearing load acts on the axis C ₁ of the clip C, making it susceptible to breakage, which poses a problem that it cannot be adopted suddenly. Ta.

This invention was devised in view of the current situation, and its purpose is to simplify the work of fixing the bumper face to the bumper reinforcement, so that even if a collision load is applied to the bumper face, the clips will not work. It is an object of the present invention to provide a bumper face fixing structure that can maintain the fixed state of the bumper face.

In order to achieve this purpose, in this invention, the bumper face is formed to have a U-shaped cross section, and a bumper reinforcement made by bending a sheet of plate material to have a U-shaped cross section is placed on the back side of the bumper face. , the upper and lower walls of the reinforcement are brought into contact with and supported by the rear back surface of the upper wall and the rear back surface of the lower wall of the bumper face, respectively, and the bumper face is fixed by inserting clips into the through holes provided in the respective contact areas. On the other hand, the rear ends of the upper and lower walls of the bumper reinforcement are folded back outward to form locking portions that go around the rear ends of the upper and lower walls of the bumper reinforcement. A gap is formed between the bumper face and each rear end portion of the bumper face.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

In the embodiment shown in FIG. 3, the bumper face 4 is formed of a resin material and has a substantially U-shaped cross section.
Through holes 7 and 8 for inserting the clip C are provided at the rear of the upper wall 5 and the lower wall 6, respectively.

On the other hand, on the back side of the bumper face 4, a bumper reinforcement 9 formed by bending a single metal plate into a U-shaped cross section is arranged, and the upper wall 10 and the lower wall 11 of the bumper reinforcement 9 are connected to the bumper face. It is supported in contact with the rear back surfaces of the upper side wall 5 and lower side wall 6 of 4. Similar through holes 12 and 13 are formed in the corresponding contact portion at positions corresponding to the through holes 7 and 8 of the bumper face 4.

Further, the rear end portions of the upper wall 10 and lower wall 11 of the bumper reinforcement 9 are folded back to the outside, and the retainers that go around the rear end portions 5a, 6a of the upper wall 5 and lower wall 6 of the bumper reinforcement 4 are folded back to the outside. Stop part 1
4,15 are formed.

Here, the locking portions 14 and 15 are formed so as to protrude from the general surface of the upper side wall 10 and the lower side wall 11, and are located at the respective rear end portions 5 of the bumper face 4.
There is a gap 16, 1 between the front and back surfaces of a and 6a.
7. In this way, the locking parts 14, 15
By protruding and forming the locking portion 14,
In addition to preventing the spring back of the bumper reinforcement 9, the rear end portions 5a and 6a are not restrained by the gaps 16 and 17 when the bumper reinforcement 4 is installed, and the bumper reinforcement 4 is not affected by the unevenness in the molding of the bumper reinforcement 9. It will not be done. In addition, the reference numeral 18 in the figure is a concealing flange that covers the end of the locking portion 14.

When fixing the bumper face 4 to the bumper reinforcement 9 configured as described above, first attach the bumper face 4 to the bumper reinforcement 9.
and each upper wall 5, 10 and lower wall 6, 1
The through holes 7, 12 and 8, 13 provided in the bumper face 4 are aligned so that they are concentric, and the rear ends 5a, 6a of the upper and lower side walls 5, 6 of the bumper face 4 are aligned.
the corresponding locking part 1 of the bumper reinforcement 9
4, 15, and then the through holes 7, 12.
8 and 13 from the bumper reinforcement 4 side, and by engaging the locking legs 19 with the periphery of the through holes 12 and 13 of the bumper reinforcement 9, the bumper reinforcement 4 is attached to the bumper reinforcement 9. stick.

Therefore, in this embodiment, even if the collision load F acts on the front surface of the bumper face 4,
Since the rear ends 5a, 6a of the upper and lower side walls 5, 6 of the bumper face 4 engage with the locking parts 14, 15, rearward movement is restricted, and shock absorption can be achieved sufficiently. .

In addition, in the above case, no load in the shearing direction is applied to the clip C, and it is sufficient to restrict the lifting of the bumper face 4, so that the clip C can withstand sufficient resistance without using conventional fixing means using bolts and nuts. This makes it possible to perform the fixing work easily, and also when removing the bumper face from the bumper reinforcement 9, the locking leg 1 of the clip C can be
9 into the through holes 12 and 13 of the bumper reinforcement 9
It can be easily removed by simply disengaging it. Furthermore, not only can the clip C be made smaller, but also the appearance quality can be improved if the head of the clip C is made of the same quality and color material as the bumper face 4.

As explained above, according to the bumper faceia fixing structure according to the present invention, the work of fixing the bumper faceia is extremely simple compared to the conventional fastening means using bolts and nuts, and it is also effective against collision loads acting on the bumper faceia. It has a fixed structure that is durable enough.

In addition, it is possible to easily remove the bumper face when replacing the bumper face or bumper reinforcement, and the gap provided between the bumper face and the locking part of the bumper reinforcement allows the bumper reinforcement to be easily removed. Since the bumper face is not affected by the unevenness of the molding, it is possible to prevent the bumper face from waving, etc., and the appearance is improved.
