Problems solved by technology

Therefore, for example, when a load is input to the apron from the lower side of the vehicle of the apron, the load is directly transmitted from the apron to the cooling duct, whereby the cooling duct may be deformed together with the apron.

Abstract

In a vehicle lower part structure, a flow path for coolant is constituted by a tray bottom portion of a tray on which a battery is installed and second recesses of a plate. A flat plate portion of a protector is disposed on the vehicle lower side of the plate, and the flat plate portion is connected to bottom portions of first recesses of the plate with bolts. The first recesses have a larger depth than the second recesses and the bottoms of the first recesses are located lower than those of the second recesses. Thus, the flat plate portion of the protector is separated downward from the bottoms of the first recesses.

Description

technical field [0001] The present invention relates to a vehicle underbody structure in which a battery case is disposed on a vehicle underside of a vehicle. Background technique [0002] For example, in the configuration disclosed in Japanese Patent Application Laid-Open No. 2015-224027 described below, the cross-sectional shape of the cooling duct is, for example, a substantially U-shape opening toward the upper side of the vehicle. A support plate constituting the base body is disposed on the opening side of the cooling duct, and the opening side of the cooling duct is closed by the support plate. In addition, the base body is provided with a substantially flat plate-shaped guard (protector). In the first embodiment of Japanese Patent Application Laid-Open No. 2015-224027, the cooling duct is disposed inside the groove formed in the guard plate, and in the second embodiment of Japanese Patent Laid-Open No. 2015-224027, the cooling duct is disposed on the guard plate. I...
