Description

  The present invention relates to an opening structure of an electrical equipment storage box.

  In recent years, diesel-electric hybrid engines have been developed. This type of diesel-electric hybrid engine incorporates an ultra-thin three-phase AC machine in the flywheel housing of the diesel engine. The three-phase alternator is operated as a starter, the three-phase alternator is operated as a torque assist motor when the vehicle is accelerated, and the three-phase alternator is operated as an electric brake when the vehicle is braked. By assisting the diesel engine, the burden on the diesel engine is reduced, the fuel consumption is improved, and the emission amount of air pollutants by the diesel engine is reduced.

  In a hybrid vehicle equipped with such a diesel-electric hybrid engine, it is necessary to mount a battery for driving a motor (nickel metal hydride battery), and this battery must be able to be efficiently air-cooled. In particular, when the hybrid vehicle is a cab overtrack or the like, it is difficult to mount the battery on the cab side, so that the battery pack (electric component storage box) 1 is attached to the chassis frame 2 as shown in FIG. It is designed to be mounted via the bracket 3.

  The battery pack 1 contains a battery (electrical component) 4 composed of a large number of battery modules 4 a, and the outside air 6 taken in from the intake port (opening) 5 is passed through the U-shaped flow path of the intake duct 7. The battery 4 is guided to the blower 8 through the blower 8 and directly below the battery 4, and is passed between the battery modules 4 a and extracted upward, so that the battery 4 is forcibly cooled by air. The outside air 6 extracted to the outside is discharged to the outside through an exhaust port 9 opened in the side wall 1a of the battery pack 1 on the side opposite to the intake port 5.

  Here, the air inlet 5 of the battery pack 1 is provided with a louver plate in which a plurality of rows of louvers are arranged, and each louver of the louver plate enters water from the outside when the outside air 6 is taken into the intake duct 7. I try to suppress it.

  The prior art document information related to this type of battery pack 1 includes the following Patent Document 1.

  When rain water or the like wound up by the tire is applied to the battery pack 11, the water on the upper surface 13 a of the upper cover 13 is blocked by the recess A, and when a part of the water flows toward the intake port 15, The bowl-shaped gap allows water to flow outward from the side of the intake port 15 and prevents water from entering the battery pack 11 from the intake duct 7. Further, when water such as rainwater flows from the side of the upper cover 13 toward the opening of the louver plate 17, the bowl-shaped gap of the side convex portion 20 allows water to flow outward from the lower portion of the intake port 15. Intrusion of water from the duct 7 into the battery pack 11 is prevented. On the other hand, when water such as rain water wound up by the tires scatters from below toward the air intake 15, the lower flange 21 bounces the water back from the air intake 15 and the intake duct 7 into the battery pack 11. Prevent water ingress.

  Thus, according to the first example of the embodiment as described above, the convex portion 18 of the intake port 15 causes the water flowing toward the intake port 15 to flow outward from the intake port 15 and into the battery pack 11. Therefore, the electrical component housed in the battery pack 11 can be appropriately protected from intrusion water.

  The convex portion 18 includes an upper side convex portion 19 that prevents inflow of water from the upper side to the intake port 15, and a front side (one side) side that prevents inflow of water from the front side (side) to the intake port 15. When the side protrusions 20 are formed, the water flowing from the upper side and the front side (side) of the battery pack 11 toward the intake port 15 flows to the outside of the intake port 15 to prevent water from flowing into the battery pack 11. Therefore, the electrical component accommodated in the battery pack 11 can be more appropriately protected from intrusion water. When the upper side convex part 19 and the side side convex part 20 continuously form an L-shaped convex body, the battery pack is protected against water flowing from the upper side and side of the battery pack 11 toward the air inlet 15. Inflow of water into 11 can be suitably prevented.

  Further, when the convex portion 18 is a mating flange 21 disposed on the lower side of the air inlet 15 so as to prevent water from flowing from the lower side to the air inlet 15, water flowing from the lower side of the battery pack 11 toward the air inlet 15. Is caused to flow outward from the air intake port 15 to prevent water from flowing into the battery pack 11, so that the electrical components housed in the battery pack 11 can be more appropriately protected from intrusion water.

  Furthermore, by providing the concave portion A as a ridge on the upper surface 13a of the upper cover 13, the flow of water to the intake port 15 can be prevented, and the inflow of water into the battery pack 11 can be suitably prevented in combination with the convex portion 18. .
