Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bumper arrangement structure in a vehicle such as an automobile.
[0002]
[Prior art]
Bumpers are usually disposed at the front and rear end portions of automobiles mainly for the purpose of protecting functional parts such as body bodies, radiators, air conditioner capacitors, lamps and the like.
[0003]
[Problems to be solved by the invention]
In general, a bumper for a vehicle such as a front bumper of an automobile is often formed to have a thin thickness and a depth width W (refer to FIG. 1) in a longitudinal direction of the vehicle body in accordance with a design requirement. In such a case, the rigidity of the entire bumper tends to be insufficient. In such a bumper having many flat portions with low surface rigidity, there is a possibility that deformation of the bumper (depression generated when the bumper is locally pushed) may be a problem.
[0004]
For short bonnet models, clearance C between the front bumper and the air conditioner capacitor (see Fig. 4) and between the front bumper and the radiator due to component layout or design restrictions. There may be cases where sufficient clearance cannot be obtained. In such a case, for example, the front bumper is greatly deformed due to a slight collision such as when the bumper hits an obstacle lightly when driving at a low speed such as when entering a garage, and the rigidity is locally high. There is a risk that the bumper portion (the flange portion forming the running wind intake opening) hits internal fitting parts such as an air conditioner condenser disposed at the rear portion of the front bumper and breaks them.
[0005]
The present invention has been made in view of such a situation, and an object of the present invention is to provide a locally stiff portion of the bumper when the bumper is deformed by a slight collision force acting on the bumper ( It is possible to avoid that the flange part that forms the running wind intake opening) hits the heat-dissipating fin (the part that has the lowest rigidity and is most susceptible to damage) on the front surface of the air conditioner condenser or radiator, thereby protecting the internal equipment parts. It is an object of the present invention to provide a bumper arrangement structure having such a configuration.
[0006]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, in the present invention, the bumper body or the bumper grille assembled to the bumper body is disposed in a state of projecting from the rear surface of the bumper body or the bumper grille toward the rear side and in the vertical direction. Provided with a pair of ribs arranged at intervals in the vehicle width direction, and arranged with an air conditioner condenser and a radiator arranged side by side along the vehicle width direction behind the bumper body and the pair of ribs, one of the ribs of said pair of ribs, a portion between the air conditioner condenser and the radiator and the air conditioning condenser with a front of the radiator, and is arranged in front of the air conditioner condenser and the radiator the air-conditioning condenser or radio off in the vehicle width direction from the condenser fins and the radiator fins It arranged so as to correspond to the rigid portion of the over data, the other rib of the pair of ribs, and the rigid portion to a position corresponding to the side of the air conditioner condenser or radiator opposite, and The capacitor fin or the radiator fin is arranged at a position deviating in the vehicle width direction .

[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
[0008]
FIG. 1 shows a configuration of a vehicle body front portion of an automobile 1 having a bumper arrangement structure according to an embodiment of the present invention. The automobile 1 is of a type having a short bonnet (front hood) 2 at the front, and a bumper (front bumper) 3 is disposed along the vehicle width direction at the bottom of the bonnet 2.
[0009]
As shown in FIGS. 1 and 2, the bumper 3 described above is fitted and disposed in a bumper body 4 made of a synthetic resin and a running wind intake opening 5 provided at a substantially central portion of the bumper body 4. The bumper grill 6 is made of synthetic resin.
[0010]
On the other hand, as shown in FIG. 1, a radiator 8 and an air conditioner condenser 9 are juxtaposed on the first cross member 7 at the front of the vehicle body, and between the radiator 8 and the air conditioner condenser 9 are shown in FIGS. Thus, a buffer material (buffer pad) 10 is interposed. Further, a receiver dryer 11 for an air conditioner is installed at a side portion of the air conditioner condenser 9 opposite to the radiator 8 (see FIGS. 1, 3 and 4). And the bumper 3 is attached to the front near position of these radiator 8, the air-conditioner capacitor | condenser 9, and the receiver dryer 11 in the opposing state. 3 and 4, reference numeral 20 denotes a dash panel that partitions the passenger compartment 21.
[0011]
In addition, a pair of left and right ribs 12 a and 12 b that are also used as air guide plates for the air conditioner capacitor 9 are integrally formed on the back surface 4 a of the bumper body 4. The ribs 12 a and 12 b are integrally formed with the air conditioner capacitor 9. Are arranged corresponding to the left and right side portions in front of each other.
[0012]
More specifically, the rib 12a of the pair of ribs 12a and 12b is a part of the flange portion 4b of the bumper body 4 that forms the running wind intake opening 5 as shown in FIGS. A portion that substantially corresponds to the side portion P (see FIG. 4) and that extends along the vertical direction at the upper portion of the one side portion P and protrudes from the back surface 4a of the bumper body 4 toward the rear side. It is arranged in the state. The rib 12b of the pair of ribs 12a and 12b corresponds to an intermediate portion in the left-right direction of the traveling wind intake opening 5 and is located at an upper portion of the traveling wind intake opening 5. The bumper main body 4 is provided so as to extend along the vertical direction and to protrude rearward from the back surface 4a of the bumper body 4. Thus, these plate-like ribs 12 a and 12 b are arranged to face each other in parallel, and the width between them is set slightly wider than the lateral width of the air conditioner capacitor 9.
[0013]
When the bumper 3 is attached to the first cross member 7 at the front of the vehicle body, as shown in FIG. 3, the rib 12a is disposed corresponding to the receiver dryer 11, and the rib 12b is provided with the radiator 8 and the air conditioner condenser 9. It is arranged corresponding to the cushioning material 10 between. In this case, the protruding end of the rib 12a is disposed corresponding to the portion of the receiver dryer 11 near the air conditioner capacitor 9 (the side portion facing the side surface of the air conditioner capacitor 9), and the protruding end of the rib 12b. Is arranged corresponding to the central portion of the cushioning material 10.
[0014]
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 introduces traveling air to the front surface of the air conditioner capacitor 9. The ribs 12a and 12b can be integrally formed so that the rigidity of the bumper body 4 can be increased. Moreover, not only can the rigidity of the bumper body 4 be increased, but also the receiver dryer can be moved by shifting the installation position of the pair of ribs 12a and 12b from the heat dissipating fin position (capacitor fin position) on the front surface of the air conditioner condenser 9 which is easily damaged. 11 and the cushioning material 10 are arranged correspondingly in front of each other. Therefore, when the bumper 3 is deformed in a minor collision that does not affect the occupant, the rib 12a hits the receiver dryer 11 and the rib 12b Therefore, the bumper 3 can be prevented from hitting the air-conditioning condenser 9 with a locally rigid portion of the bumper 3 (that is, the flange portion 4b of the bumper body 4).
[0015]
At this time, since the rib 12b hits the cushioning material 10, the rib 12b serves as a so-called “sticker rod”, and the deformation amount of the bumper 3 at the time of a slight collision is reduced to a small deformation amount as indicated by L in FIG. Can be suppressed. Further, the rib 12a arranged at the opposite position where the cushioning material 10 is not installed is such that the locally stiff portion of the bumper 3 (that is, the flange portion 4b of the bumper body 4) is the air conditioner condenser 9 or the radiator 8. Since the relatively soft rib 12a hits the high-rigidity receiver dryer 11 before hitting, the impact force acting on the bumper 3 due to a slight collision can be absorbed, and the degree of damage to the air conditioner condenser 9 and the radiator 8 is reduced. can do.
[0016]
As described above, according to the present embodiment, by using the bumper-integrated air conditioning capacitor air guide plate that has been used conventionally as the ribs 12a and 12b, the rigidity of the bumper 3 can be increased, and a slight collision can be achieved. Since the deformation amount L of the bumper 3 at this time can be suppressed to a low level, the degree of damage to the internal equipment components such as the radiator 8 and the air conditioner capacitor 9 can be suppressed to a low level.
[0017]
Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various modifications and changes can be made based on the technical idea of the present invention. For example, in the embodiment described above, the bumper body 4 is provided with the pair of ribs 12a and 12b. However, the bumper grille 6 assembled in the running wind intake opening 5 of the bumper body 4 or the running wind intake. The pair of ribs 12a and 12b as described above may be provided on the back surface of a bumper grill (not shown) disposed at a bumper upper portion above the opening 5 for use. The shape of the pair of ribs 12a and 12b can be changed as appropriate. Further, it is not always necessary to dispose the rib 12b corresponding to the cushioning material 10, and the rib 12b corresponds to a rigid portion such as a side portion of the outer peripheral frame of the air conditioner capacitor 9 that is removed from the capacitor fin on the front surface of the air conditioner capacitor 9. It may be arranged so as to.
[0018]
In the above-described embodiment, the pair of ribs 12a and 12b corresponding to the air conditioner capacitor 9 is provided, but the pair of ribs corresponding to the radiator 8 is provided in the bumper body 4, and one of the ribs is used as a cushioning material. 10, and the other rib is disposed on the side of the radiator 8 on the side opposite to the cushioning material 10 (for example, the side of the outer peripheral frame of the radiator 8 that is removed from the heat radiation fin (radiator fin) on the front surface of the radiator 8). A portion) or a portion in the vicinity of the side (for example, a rigid portion of another part disposed on the side of the radiator 8). Also in this case, as in the case of the above-described embodiment, it is possible to protect internal equipment components such as the radiator 8 and the air conditioner capacitor 9 in the case of a slight collision.
[0019]
Further, the pair of ribs 12a and 12b provided on the back surface 4a of the bumper body 4 or the back surface of the bumper grill 6 do not necessarily need to be constituted by a single vertical rib. As shown in FIG. , 12b is provided with a pair of upper and lower horizontal ribs 30 and 31 arranged in a horizontal direction at a substantially right angle, and rear end surfaces 30a and 31a of these horizontal ribs 30 and 31 are connected to the air conditioner condenser 9 or the radiator 8 respectively. You may arrange | position so that it may correspond to the side part (The rigid location of the position remove | deviated from the capacitor | condenser fin or the radiator fin) M. In this case, even if the bumper 3 is deformed at the time of a slight collision, the rear end surfaces 30a, 31a of the lateral ribs 30, 31 surely contact the side portion M, so that the ribs 12a, 12b are detached from the side portion M and the capacitor Problems such as hitting the fins or the radiator fins can be reliably prevented. Moreover, the rigidity of the ribs 12a and 12b can be increased by providing the pair of upper and lower lateral ribs 30 and 31.
[0020]
Further, in the above-described embodiment, the pair of ribs 12a and 12b are provided on the front bumper 3, but a pair of ribs 12a and 12b are provided on the rear bumper, and protection of internal fitting parts disposed corresponding to the rear bumper is provided. You may make it plan.

【The invention's effect】
The present invention according to claim 1 is disposed on the bumper body or the bumper grille assembled to the bumper body so as to protrude rearward from the back surface of the bumper body or the bumper grille, and extends vertically. And a pair of ribs arranged at intervals in the vehicle width direction, and an air conditioner condenser and a radiator arranged side by side along the vehicle width direction behind the bumper body and the pair of ribs , one of the ribs of the ribs, a portion between the air conditioner condenser and the radiator and the air conditioning condenser with a front of the radiator and condenser fins the respectively disposed in front of the air conditioner condenser and the radiator and rigidity箇of the air conditioner condenser or radiator from the radiator fins outside in the vehicle width direction Arranged so as corresponding to said the other rib of the pair of ribs, and the rigid portion to a position corresponding to the side of the air conditioner condenser or radiator opposite, and the capacitor fin or Since it is arranged at a position that deviates from the radiator fin in the vehicle width direction, in the case of a minor collision that does not affect the occupant, one rib hits a rigid part that is separated from the condenser fin or radiator fin, so-called Since it will serve as a “sticker rod”, a locally stiff part of the bumper (for example, running wind intake) on the condenser fin or radiator fin (the most easily damaged part) on the front of the air conditioner condenser or radiator The flange part that forms the opening of the air-conditioner) It is possible to achieve the protection of instrumentation parts. Furthermore, since the rigidity of the bumper itself is increased with the provision of the pair of ribs on the bumper body, the amount of deformation of the bumper at the time of a slight collision can be reduced.
[0022]
In the present invention according to claim 2, the one rib is disposed so as to correspond to a buffer material interposed between an air conditioner capacitor and a radiator, and the other rib is connected to the buffer material. 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 disposed on the side portion of the air-conditioner condenser on the opposite side, which affects the occupant In the case of a minor collision with no air conditioner, one rib hits the cushioning material (rigid part) and acts as a so-called “sticker rod”, and the other rib hits the receiver dryer (high rigidity part). A locally stiff part of the bumper (for example, traveling wind) on the condenser fin or radiator fin (the most easily damaged part) on the front surface of the condenser or radiator Since it is possible to prevent the flange portion) hits to form a necessity opening, it can be protected inside outfitting components such as air conditioning condenser.
[0023]
Further, the present invention according to claim 3 uses a wind guide plate integrally formed on the bumper body or the bumper grill in order to introduce the traveling wind to the front surface of the air conditioner condenser or the radiator as the pair of ribs. By using the conventional air guide plate for air conditioner condenser or radiator (existing air guide plate rib), the bumper rigidity can be increased and the deformation of the bumper at the time of minor collision can be suppressed to a minimum. In addition, it is possible to reduce damage to the internal equipment parts such as the air conditioner condenser and the radiator from the bumper.
[0024]
According to a fourth aspect of the present invention, the pair of ribs are configured as vertical ribs, a horizontal rib is attached to the pair of ribs formed of the vertical ribs, and a rear end surface of the horizontal rib is used as the rigid portion. Since the rear end surface of the lateral rib reliably hits the rigid portion that has been removed from the capacitor fin or the radiator fin when the bumper is deformed during a minor collision, the pair of ribs (vertical It is possible to prevent such a problem that the rib) hits the capacitor fin or the radiator fin and damages them. And the rigidity of a pair of said rib (vertical rib) can be improved by providing a horizontal rib.
