Abstract

PROBLEM TO BE SOLVED: To provide a disposition structure of a bumper capable of preventing a local high-rigidity portion of the bumper (flange part for forming an opening for taking running wind) from a butting on a radiating fin (portion having low rigidity which is most liable to be damped) in the front of an air conditioner condenser or a radiator and protecting the internal fitting-out parts when light collision force is applied to the bumper to deform the bumper. SOLUTION: A bumper body 4 or a bumper grille 6 assembled to the bumper body is provided with a pair of ribs 12a, 12b, one rib 12b of the paired ribs 12a, 12b is disposed corresponding to a buffer material 10 interposed between the air conditioner condenser 9 and the radiator 8, and the other rib 12a of the paired ribs 12a, 12b is disposed corresponding to a receiver dryer 11 disposed on the side portion of the air conditioner condenser 9 on the opposite side to the buffer material 10.

Generally, a bumper for a vehicle such as a front bumper of an automobile has a small thickness, that is, a depth width W in the front-rear direction of the vehicle body (see FIG. 1) due to design requirements and is flat. In many cases, the rigidity of the bumper as a whole tends to be insufficient. In a bumper having such a flat surface portion with low surface rigidity, deformation of the bumper (dent generated when the bumper is locally pressed) may cause a problem.

[0004] Further, in the case of a vehicle having a short hood, etc., due to restrictions on parts layout or design,
In some cases, the clearance C between the front bumper and the air conditioner condenser (see FIG. 4) and the clearance between the front bumper and the radiator cannot be sufficiently secured. In such a case, for example, only a slight collision such as a bumper lightly hitting an obstacle during low-speed traveling such as when entering a garage causes a large deformation of the front bumper and a locally high rigidity. There is a possibility that the bumper portion (the flange portion forming the opening for taking in the traveling wind) hits internal fittings such as an air conditioner condenser arranged at the rear of the front bumper, and damages them.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to reduce the rigidity of a bumper locally when the bumper is deformed by a small impact force acting on the bumper. High parts (flanges forming the opening for intake of traveling wind) can be prevented from hitting the radiating fins (points with low rigidity and most susceptible to damage) on the front of the air conditioner condenser or radiator. An object of the present invention is to provide an arrangement structure of a bumper having a configuration capable of providing protection.

According to the arrangement structure of the bumper 3 having such a configuration, the pair of ribs 12 a and 12 b integrally formed on the back surface 4 a of the bumper main body 4 serve to introduce the traveling wind to the front surface of the air conditioner condenser 9. The ribs 12a, 12b can be installed so as to function as a wind guide plate, and the rigidity of the bumper main body 4 can be increased by integrally forming the ribs 12a, 12b. Moreover, not only can the rigidity of the bumper body 4 be increased, but also the position of the heat dissipating fins (the position of the condenser fins) on the front surface of the air conditioner condenser 9 that is easily damaged.
The bumpers 3 are deformed in the event of a minor collision that does not affect the occupant since the installation positions of the pair of ribs 12a and 12b are shifted from each other so as to correspond to the front of the receiver dryer 11 and the cushioning material 10, respectively. The rib 12a hits the receiver dryer 11 and the rib 1
2b hits the cushioning material 10, so that the bumper 3
A locally rigid portion (that is, the flange portion 4b of the bumper body 4) can be prevented from hitting the air conditioner condenser 9.

At this time, since the rib 12b hits the cushioning material 10, the rib 12b functions as a so-called "stick rod", and the amount of deformation of the bumper 3 at the time of a slight collision is small as indicated by L in FIG. The amount of deformation can be suppressed. The ribs 12a disposed on the opposite side where the cushioning material 10 is not installed are provided in such a manner that the locally rigid portion of the bumper 3 (that is, the flange portion 4b of the bumper main body 4) is used for the air conditioner condenser 9 and the radiator 8. Before hitting, the relatively soft rib 12a hits the high-rigidity receiver dryer 11, so that it can absorb the collision force acting on the bumper 3 due to the slight collision and reduce the degree of damage to the air conditioner condenser 9 and the radiator 8. can do.

According to the first aspect of the present invention, a pair of ribs are provided on a bumper main body or a bumper grill attached to the bumper main body, and one of the pair of ribs is replaced with a rib.
At a location between the air conditioner condenser and the radiator, and disposed so as to correspond to a rigid place deviated from the condenser fin and the radiator fin disposed on the front surface of the air conditioner condenser and the radiator, respectively, The other rib is located at a position corresponding to the side of the air conditioner condenser or the radiator opposite to the rigid portion and at a position separated from the condenser fin or the radiator fin. In the event of a minor collision that does not affect the occupants, one rib will act as a so-called "stick rod" when it hits a rigid part that has deviated from the condenser fin or radiator fin. Condenser fins or radiator fins (most It is possible to prevent a locally rigid portion of the bumper (for example, a flange portion that forms a driving wind intake opening) from hitting the bumper (a portion that is easily damaged), thereby protecting internal fittings such as an air conditioner capacitor. Can be planned. Further, the rigidity of the bumper itself is increased with the provision of the pair of ribs on the bumper body, so that the amount of deformation of the bumper at the time of a slight collision can be suppressed.

According to a second aspect of the present invention, the one rib is disposed so as to correspond to a cushioning material interposed between the air conditioner condenser and the radiator, and the other rib is provided with the other rib. Since it is arranged so as to correspond to the rigid portion of the side of the radiator opposite to the receiver dryer or the cushioning material, which is disposed on the side of the air conditioner condenser opposite to the cushioning material, In the event of a minor collision that does not affect the occupant, one of the ribs hits the cushioning material (rigid portion) to serve as a so-called "patch bar" and the other rib hits the receiver dryer (high rigidity portion). For this reason, the locally high rigidity of the bumper (eg, the portion where the bumper is most likely to be damaged) is located on the condenser fin or radiator fin (the most fragile portion) on the front of the air conditioner condenser or radiator. In the flange part forming the running wind taken needful openings) it is possible to suppress the strike,
It is possible to protect internal equipment such as an air conditioner condenser.

According to a third aspect of the present invention, as the pair of ribs, an air guide plate formed integrally with the bumper body or the bumper grill for introducing a traveling wind to the front of the air conditioner condenser or the radiator is used. Therefore, by using a conventional air guide plate for air conditioner condenser or radiator (existing wind guide plate rib),
The rigidity of the bumper can be increased, the deformation of the bumper at the time of a minor collision can be reduced, and the damage to the internal fittings such as the air conditioner condenser and the radiator from the bumper can be reduced.

According to a fourth aspect of the present invention, the pair of ribs are configured as vertical ribs, and the pair of ribs formed by the vertical ribs are provided with horizontal ribs. Since it is arranged so as to correspond to the rigid portion, the rear end surface of the lateral rib surely hits the rigid portion deviated from the condenser fin or the radiator fin when the bumper is deformed at the time of a minor collision, so It is possible to prevent the ribs (vertical ribs) from hitting the condenser fin or the radiator fin and damaging them. Moreover, the rigidity of the pair of ribs (vertical ribs) can be increased by providing the horizontal ribs.
