It is housed in.

Next, the configuration of the cooling assembly 10 will be described with reference to FIGS. 4 and 5.
FIG. 4 is a perspective view of the cooling assembly 10 as viewed from the obliquely rear side of the vehicle. FIG. 5 is a perspective view of the cooling assembly 10 as viewed from the front side of the vehicle.

As shown in FIG. 4, the cooling assembly 10 includes a radiator 14, a fan 16 attached to the back side of the radiator 14, and an oil cooler 18 arranged on the back side of the fan 16. The radiator 14, the fan 16, and the oil cooler 18 are integrated to form an assembly. Further, support members 20 for supporting the integrated radiator 14 and the like on the vehicle body of the vehicle 1 are attached to both side surfaces of the radiator 14.

As shown in FIG. 1, the cooling assembly 10 is located in front of the vehicle with respect to the in-wheel motor 8. Therefore, the oil cooler 18 is arranged between the radiator 14 and the wire harness 8a which is a high voltage component. As a result, even if the vehicle 1 collides from the front and the radiator 14 comes off from the support member 20, the oil cooler 18 is arranged between the wire harness 8a and the radiator 14 on which the high voltage is applied. The wire harness 8a is protected from impact. Further, since the internal combustion engine 2 is arranged behind the wire harness 8a, the wire harness 8a is arranged between the oil cooler 18 and the internal combustion engine 2.

As shown in FIGS. 4 and 5, the radiator 14 is formed in a rectangular flat plate shape as a whole, and is attached to the vehicle body of the vehicle 1 so that the plate surface is inclined toward the rear. Further, in the present embodiment, the radiator 14 is provided with radiator tanks 14a along the edges on both sides thereof, and radiator cores 14b are provided between the radiator tanks 14a on both sides. In the present embodiment, the radiator 14 is configured to cool the cooling water of the internal combustion engine 2 by the outside air.

As shown in FIG. 4, the fan 16 is fixed to the back side of the radiator 14 in parallel with the radiator 14, and is composed of a frame 16a and a propeller 16b. The propeller 16b has a diameter substantially the same as the width of the radiator core 14b, and is driven by a rotation axis (not shown) oriented in a direction orthogonal to the plate surface of the radiator 14. The frame 16a is fixed to the back side of the radiator core 14b and supports the rotation axis of the propeller 16b. By rotating the propeller 16b, air flows through the radiator core 14b, and the cooling water in the radiator core 14b is cooled.

As shown in FIG. 4, the oil cooler 18 is formed in the shape of a rectangular flat plate smaller than the radiator 14, and is attached to the back side of the fan 16 so that the plate surface inclines toward the rear. .. An inflow pipe 18a for flowing cooling oil into the oil cooler 18 and an outflow pipe 18b for flowing out the cooling oil cooled by the oil cooler 18 are connected to both upper ends of the oil cooler 18. Further, as shown in FIG. 5, the oil cooler 18 is arranged at a position overlapping with the radiator 14 in the front view of the vehicle 1.

In the present embodiment, the oil cooler 18 is configured to cool the cooling oil that cools the drive motor 4, the battery (not shown) for driving the drive motor 4, and the like. Further, the oil cooler 18 is attached to the support member 20 via an upper oil cooler bracket 18c attached to the upper side thereof and a lower oil cooler bracket 18d attached to the lower side thereof.

As shown in FIG. 4, the support member 20 is a member bent in a substantially L shape, and is attached to both sides of the radiator 14 in order to fix the cooling assembly 10 to the first cross member 12a of the vehicle body. ing. Specifically, the support member 20 is composed of a circular tubular member bent at an acute angle smaller than 90 degrees, and its long side is fixed along both sides of the radiator 14. Further, the shorter side of the support member 20 is generally oriented in the horizontal direction when the cooling assembly 10 is fixed to the vehicle body. As a result, the radiator 14 and the oil cooler 18 are attached to the vehicle body so that their plate surfaces are inclined toward the rear. In other words, the radiator 14 and the oil cooler 18 are arranged so as to be tilted backward so that their upper ends are located on the rear side of the vehicle 1 with respect to the lower ends.

Further, as shown in FIG. 2, each support member 20 is connected to each other in the vicinity of the bent portion by a connecting beam 22. Specifically, the connecting beam 22 extends in the vehicle width direction and is attached to the support member 20 via the lower oil cooler bracket 18d attached to each support member 20 to connect the support members 20 on both sides. .. The connecting beam 22 is attached to the short side of each support member 20 in the vicinity of the bent portion.

Further, as shown in FIG. 4, the long side of each support member 20 is fixed to the radiator tanks 14a on both sides of the radiator 14 via the upper bracket 20a and the lower bracket 20b. Since the radiator tank 14a is located at both ends of the cooling assembly 10 in the vehicle width direction, the cooling assembly 10 is supported by the support members 20 at both ends thereof. Further, support portions 20c are provided at the tips of the short sides of each support member 20, and these support portions 20c are rotatably attached to the first cross member 12a forming a part of the vehicle body. It is configured to be able to.

Further, as shown in FIG. 3, the short sides of each support member 20 are oriented so as to widen the distance toward the front of the vehicle 1. In other words, the vehicle width direction spacing X1 of the first connection point P1 connecting the support portion 20c of each support member 20 and the first cross member 12a connects each support member 20 and the radiator 14. It is configured to be narrower than the vehicle width direction distance X2 of the two connection points P2.

Since the cooling assembly 10 is formed as described above, in the unlikely event that the vehicle 1 collides head-on, an impact force is first applied to the radiator 14 arranged at the front portion of the vehicle 1, and the radiator 14 is deformed. The impact energy is absorbed by being done. When the impact force is further large, the upper bracket 20a and the lower bracket 20b that connect the radiator 14 and the support member 20 are broken, or the connection between them is disconnected, so that the impact energy is absorbed. At this time, an impact force acts on the lower end of the radiator 14 which is tilted backward, the lower bracket 20b is disengaged, and the lower portion of the radiator 14 retracts. If the impact force is further large, the upper bracket 20a also comes off, and the entire radiator 14 retracts.

Even if the radiator 14 falls off from the support member 20 and the entire radiator 14 retracts, the oil cooler 18 is prevented from retracting because the oil cooler 18 is attached to the rear of the radiator 14. As a result, damage to the wire harness 8a, which is a high-voltage component arranged behind the oil cooler 18, is suppressed. Further, even if the upper oil cooler bracket 18c and the lower oil cooler bracket 18d supporting the oil cooler 18 are broken or their connection is disconnected, the impact force is absorbed by the breakage or the like, and the wire harness 8a is Be protected.

Further, as described above, the short sides of each support member 20 are oriented so as to be wider toward the front of the vehicle 1. Therefore, even if the lower bracket 20b comes off due to a head-on collision of the vehicle 1 and the lower portion of the radiator 14 begins to retreat, the support member 20 resists the retreat of the radiator 14 and the retreat of the radiator 14 is suppressed. Further, since the support members 20 on both sides are connected by the connecting beam 22, the distance between the support members 20 is widened due to the collision, and it is possible to prevent the radiator 14 from retracting during that time.

Next, a method of assembling the cooling device according to the embodiment of the present invention will be described with reference to FIGS. 6 to 10.
FIG. 6 is a diagram showing the projected length of the cooling assembly in comparison with the length of the mounting portion of the vehicle body. FIG. 7 is a flowchart showing a procedure of a method of assembling the cooling device according to the embodiment of the present invention. 8 to 10 are views showing a procedure for attaching the cooling assembly to the vehicle body.

As described above, in the present embodiment, the cooling assembly 10 is attached to the vehicle body in a state of being inclined rearward. As shown in FIG. 6, when the cooling assembly 10 is arranged in the same posture as when it is attached to the vehicle body and projected in the vertical direction, the length L1 in the vehicle front-rear direction is the first cross member 12a. It is longer than the distance L2 between and the second cross member 12b. Therefore, when the cooling assembly 10 is placed on the pallet 24 in the same posture as the posture after mounting on the vehicle body, the cooling assembly 10 can be passed between the first cross member 12a and the second cross member 12b. Therefore, the cooling assembly 10 cannot be housed in the vehicle body. Therefore, it is necessary to assemble the cooling assembly 10 to the vehicle body according to the assembly procedure shown in FIG.

First, in step S1 of FIG. 7, as a preparatory step, a vehicle body to which the radiator 14 is to be assembled and a cooling assembly 10 are prepared. As shown in FIG. 8, at this time, the vehicle body 13 may be in a semi-finished state, and the first cross member 12a, the second cross member 12b, the fixed member 12d, and the like are assembled so that the cooling assembly 10 can be mounted. It is good if it is in a state. On the other hand, the cooling assembly 10 is prepared in a state where the radiator 14, the fan 16, the oil cooler 18, and the like are integrated by the support member 20. Further, the cooling assembly 10 is prepared in a state where the plate surface of the radiator 14 is placed on the pallet 24 with the plate surface oriented substantially in the vertical direction. In this state, the length L3 in the vehicle front-rear direction when the cooling assembly 10 is projected in the vertical direction is shorter than the distance L2 between the first cross member 12a and the second cross member 12b.

Next, in step S2 of FIG. 7, as a housing step, the cooling assembly 10 is passed between the first cross member 12a and the second cross member 12b from below the vehicle body 13 by raising the pallet 24. It is housed in the car body. That is, in the state shown in FIG. 8, the projected length of the cooling assembly 10 in the vertical direction is shorter than the distance L2 between the first and second cross members. Therefore, when the pallet 24 is raised, the cooling assembly 10 becomes the first. It passes between the cross member 12a and the second cross member 12b and is housed in the vehicle body 13.

Further, when the pallet 24 is raised to an appropriate position, as shown in FIG. 9, the bolt holes of the support portion 20c provided at the tip on the short side side of each support member 20 and the support attached to the first cross member 12a. The bolt holes of the bracket 26 are aligned. In this state, the bolts 26a are passed through the bolt holes provided in the support portion 20c and the support bracket 26, respectively, and these are fastened. As a result, each support portion 20c of the cooling assembly 10 is rotatably attached to the vehicle body 13.

Further, in step S3 of FIG. 7, as a rotation step, the cooling assembly 10 housed in the vehicle body 13 is supported by the support member 20 so that the upper end of the cooling assembly 10 is moved to the rear of the vehicle body 13. The portion 20c is rotated rearward around the center. Specifically, the cooling assembly 10 is rotated rearward about a bolt 26a passed through each bolt hole of the support portion 20c and the support bracket 26 as a central axis. Here, in the state shown in FIG. 9, since the center of gravity of the cooling assembly 10 is on the front side of the central axis (bolt 26a), a force for rotating the cooling assembly 10 forward is exerted by gravity. Therefore, it is possible to prevent the cooling assembly 10 from being accidentally rotated backward by gravity and damaged.

When the cooling assembly 10 is rotated backward to a predetermined position, the radiator 14 of the cooling assembly 10 is tilted backward by a predetermined angle, and the cooling assembly 10 is in the posture after being mounted on the vehicle body. In this state, as shown in FIG. 10, the engaging portion 18e (FIG. 4) of the upper oil cooler bracket 18c connecting the oil cooler 18 to the support member 20 comes into contact with the fixed member 12d of the vehicle body 13.

Next, in step S4 of FIG. 7, the cooling assembly 10 is fixed to the fixing member 12d of the vehicle body 13 as a fixing step. Specifically, the engaging portion 18e of the upper oil cooler bracket 18c that is in contact with the vehicle body 13 and the fixing member 12d of the vehicle body 13 are fastened with bolts 28 to fix the cooling assembly 10 to the vehicle body 13. Further, the bolt 26a that fastens the support portion 20c of the support member 20 and the support bracket 26 is retightened, and the assembly of the cooling assembly 10 to the vehicle body is completed.

(Fig. 1). Therefore, when the vehicle 1 collides from the front, it is possible to prevent the radiator 14 that has fallen off from the mounting position from directly interfering with the wire harness 8a arranged at the rear. As a result, the energy of the collision is consumed when the fallen radiator 14 interferes with the oil cooler 18, and it is possible to prevent an excessive impact force from being applied to the wire harness 8a arranged behind the oil cooler 18. ..

Further, according to the vehicle cooling device of the present embodiment, the oil cooler 18 is arranged at a position overlapping the radiator 14 in the front view of the vehicle 1 (FIG. 5), so that when the vehicle 1 collides from the front. The impact can be reliably mitigated by the oil cooler 18.
