Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixing device for a side portion of a resin bumper, among bumpers attached to the front and rear ends of an automobile.

In recent years, bumpers for the safety of people and objects have been made of resin, and when installing the bumper on the vehicle body, for reasons of strength, in addition to installing the bumper, it is necessary to provide reinforcement by integrally installing a steel plate and using mounting bolts, etc. Since it was fixed to the vehicle body, the bumper itself became heavy and the advantages of a resin bumper, such as being lightweight and having good shock absorption, were lost, and with the resin bumper alone, it was only held in place with bolts, etc. In this case, the bumper became unstable and had to be stopped at several places, which was a hassle.

The present invention has been devised in order to solve the above-mentioned conventional problems, and it is a bumper side that prevents the bumper from wobbling and is easy to install without impairing the characteristics of the resin bumper. The purpose is to provide a fixing device for

The present invention will be described below with reference to illustrative embodiments.

Reference numeral 1 denotes a bumper, and bumper sides 1a are formed on both sides of the bumper 1. The bumper sides 1a are molded from resin, and have a bumper side vertical surface 1d extending vertically substantially parallel to the side surface of the vehicle body. , the bumper side vertical surface 1
Bumper side upper part 1b extending toward the vehicle body from the upper end of d
and a bumper side lower part 1c extending toward the vehicle body from the lower end of the bumper side vertical surface 1d.

A is a bumper side fixing device made of resin for fixing the bumper side 1a formed of resin to the vehicle body A, which is located on both sides of the bumper 1, and is fixed to the fender 3 side forming the side surface of the vehicle body. It consists of a bumper side mounting bracket 4, and a bumper side support bracket 2 that is fixed to the bumper side 1a, supports the bumper side 1a, and is attached to the bumper side mounting bracket 4.

The bumper side mounting bracket 4 is provided with a locking groove slit 5 which is open at one end toward the rear of the vehicle in the case of a rear bumper (towards the front of the vehicle in the case of a front bumper). ing.

The bumper side support bracket 2 is formed separately from the bumper side 1a, is fixed to the bumper side 1a by a fixing device such as a bolt/nut 7, and is in contact with the bumper side upper part 1b, so that the bumper side upper part 1b is fixed to the bumper side support bracket 2. The upper support surface 2a and the bumper side lower part 1c are brought into contact with each other for support from the back side, and the bumper side lower part 1
A lower support surface 2b that supports c from the back surface, and both support surfaces 2a
, 2b protrudes toward the side of the vehicle body, and has a locking portion 6 that is inserted into the slit 5 formed in the bumper side mounting bracket 4 from the rear of the vehicle body, and the upper support surface 2a and the lower support surface It is formed into a substantially W-shaped cross section by the surface 2b and the locking portion 6 that protrudes toward the side surface of the vehicle body between the supporting surfaces 2a and 2b.

The locking portion 6 has a locking recess 6 that protrudes toward the fender 3 side.
A resin locking member 6a having a shape b formed thereon is fixed, and a locking recess 6b is fitted into the slit 5 of the bumper side mounting bracket 4, thereby fixing the bumper side 1a.

The upper support surface 2a is formed in a shape that follows the shape of the back surface of the bumper side upper part 1b, and the lower support surface 2a
b is formed in a shape that follows the shape of the back surface of the bumper side lower part 1c.

Both support surfaces 2a and 2b are fixed in advance to the bumper side upper part 1b and the bumper side lower part 1c with bolts and nuts 7.

For this reason, a large number of reinforcing ribs are provided on the resin bumper side so that it comes into close contact with the back surface of the bumper side 1a and serves as a reinforcing member to support the bumper side 1a.
By fixing the bumper side support bracket 2, the bumper side support bracket 2 can be attached to the vehicle body for reinforcement without requiring reinforcement such as integrally providing an iron plate or making the bumper thicker.

When attaching the bumper 1 to the vehicle body A, the bumper side 1a is fixed by fitting the locking tool 6a of the bumper side support bracket 2 into the slit 5 of the bumper side mounting bracket 4 on the vehicle body A side.

Incidentally, the bumper 1 is held down in the front-back direction by a bumper stay 8 in the same way as a normal bumper.

Further, as another embodiment of the present invention, as shown in FIGS. 6 to 9, the locking groove of the bumper side mounting bracket 4 on the side of the vehicle body A is replaced with the slit 5 of the first embodiment. ,
Make two cuts in the upper and lower parts of the bracket 4,
A hook-shaped locking groove 9 is formed by bending the portion sandwiched by the cut so as to protrude toward the bumper side 1a side.
The locking portion 6 of the bumper side support bracket 2 fixed to the bumper side 1a is fitted into the hook-shaped locking groove 9.

The locking portion 6 is located at the center of the bumper side support bracket 2, and is further coated with rubber or vinyl 10 to prevent rattling noise.

Also, attach the lower end of the bumper side support bracket 2 to the vehicle body A.
The flange 11 extends downward from the lower end of the bumper side mounting bracket 4, and further extends toward the bumper side 1a to form a flange 12, which is integrally formed with a bolt/nut 13. Attach and secure.

In this case, since the lower ends of both brackets 2.4 are fixed with bolts and nuts 13, there is an effect that the attachment becomes more reliable.

Note that this structure can also be adopted in the first embodiment described above.

Furthermore, in the present invention, as shown in FIGS. 3 and 4, protectors 14 made of resin or the like are provided at both ends of the bumper 1.
By installing the bumper, it is possible to adjust the gap l between the bumper and fender, which differs depending on the vehicle model, and it is possible to use a common bumper even on vehicles with different shapes of the lower part of the fender.

The shape of the protector 14 is approximately U-shaped, and a U-shaped slit 16 that opens toward the vehicle body A is inserted into a reinforcing rib 15 provided on the inside of the bumper 1. It is fixed to the bumper 1 by a screw 18 into a spring nut 17 inserted into the spring nut 17, and the fixing location can be selected as appropriate within the range of the slit 16.

As described above, the present invention attaches the bumper side to a bumper side mounting bracket that is separate from the bumper side and that is fixed to the vehicle body via a bumper side support bracket that is fixed with bolts and nuts or other fixing devices. Since it is fixed and fixed, the bumper side can be made of resin as is, so the advantages of a resin bumper can be utilized.

In addition, in the present invention, the bumper side support bracket is formed into a V-shaped cross section with an upper support surface, a lower support surface, and an engaging portion protruding toward the side of the vehicle body between the upper support surface, the lower support surface, and the middle of both support surfaces. It can make up for the shortcomings that you don't have.

Therefore, the upper support surface of the bumper side support bracket can support the upper rear surface of the bumper side, and the lower support surface of the bumper side support bracket can support the lower rear surface of the bumper side in accordance with the shapes of the upper and lower parts of the bumper side, respectively. .

Therefore, since the resin bumper side can be firmly supported, the bumper side can be prevented from wobbling and vibration, and can also serve as a reinforcing member for the bumper side.

Furthermore, in the present invention, the middle of both support surfaces of the bumper side support bracket, which also serves as reinforcement and support, is made to protrude toward the side of the vehicle body to serve as a locking part, so that the bumper side support bracket has a separate part for attaching to the side of the vehicle. Since there is no need to weld and secure attachment members of the members, the number of parts can be reduced, processing can be easily performed, and attachment to the side of the vehicle body can be easily performed.

Moreover, since there is no need for special reinforcing members like in the past, the number of parts can be reduced as well.
Since there is no reinforcing material in the entire bumper, it is lightweight, which is a characteristic of resin bumpers, and can be implemented without impairing the impact absorption effect.

Further, according to the present invention, installation is extremely easy because the locking portion of the bumper side support bracket is simply inserted into the locking groove formed in the bumper side mounting bracket.
