Abstract
Official abstract text for this publication.
A mounting structure is provided for mounting a battery pack on a floor of a vehicle cabin. The installation structure includes a bottom plate of a housing of the battery pack, cooling pipes provided inside or on a surface of the bottom plate for circulating coolant, and a plate-shaped underguard. The underguard has upwardly protruding ribs and downwardly protruding ribs that are alternately arranged. The cooling pipes are provided inside or on the surface of the bottom plate of the housing. The cooling pipes are arranged to face the downwardly protruding ribs. The underguard is attached to the housing such that a top plate of the upwardly protruding ribs and a bottom plate of the housing are spaced apart.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle mounted structure of a battery pack mounted to a floor of a vehicle cabin, the vehicle mounted structure comprising: a bottom plate of a housing of the battery pack; a plurality of cooling pipes provided to the bottom plate for circulating coolant; and a plate-shaped underguard provided below the bottom plate, the plate-shaped underguard having upwardly protruding ribs, bulges, and downwardly protruding ribs, each upwardly protruding rib or bulge is alternately arranged with each downwardly protruding rib, the cooling pipes being arranged to face the downwardly protruding ribs, the plate-shaped underguard being attached to the housing such that an upper plate of the upwardly protruding ribs and a bottom surface of the bottom plate are spaced apart from each other without any other structure therebetween, and each of the bulges contacting the bottom surface of the bottom plate and being configured to receive a fastener to secure the plate-shaped underguard to the bottom plate. 2. The vehicle mounted structure according to claim 1 , wherein the cooling pipes protrude downward from the bottom surface of the bottom plate, and a lower plate of the downwardly protruding ribs and the cooling pipes are spaced apart from each other. 3. The vehicle mounted structure according to claim 1 , further comprising a bracket forming a closed cross section together with the bottom plate protrudes downward from the bottom surface of the bottom plate, and the plate-shaped underguard is fixed to the bracket by fasteners. 4. The vehicle mounted structure according to claim 1 , further comprising a resin under cover attached to a bottom surface of the plate-shaped underguard, and the resin under cover being fixed to the bottom surface of the plate-shaped underguard by fasteners. 5. The vehicle mounted structure according to claim 2 , further comprising a bracket forming a closed cross section together with the bottom plate protrudes downward from the bottom surface of the bottom plate, and the plate-shaped underguard is fixed to the bracket by fasteners. 6. The vehicle mounted structure according to claim 2 , further comprising a resin under cover attached to a bottom surface of the plate-shaped underguard, and the resin under cover being fixed to the bottom surface of the plate-shaped underguard by fasteners. 7. The vehicle mounted structure according to claim 3 , further comprising a resin under cover attached to a bottom surface of the plate-shaped underguard, and the resin under cover being fixed to the bottom surface of the plate-shaped underguard by fasteners. 8. The vehicle mounted structure according to claim 5 , further comprising a resin under cover attached to a bottom surface of the plate-shaped underguard, and the resin under cover being fixed to the bottom surface of the plate-shaped underguard by fasteners.
