Problems solved by technology

[0004] However, since the invention described in the above-mentioned Patent Document 1 supports the battery so that it floats from the bottom surface of the recess for storing the battery, it is necessary to form a space between the bottom surface of the recess and the lower surface of the battery. The size of the recess for storage inevitably increases, resulting in a decrease in space efficiency

Abstract

A vehicular battery unit includes a battery unit body, a hollow frame, and a drain pipe. The battery unit body includes a first floor face to support a first battery. The hollow frame is disposed along the first floor face of the battery unit body to reinforce the battery unit body and has a first drain hole connecting the first floor face of the battery unit body to an interior of the hollow frame. The drain pipe extends downward from the interior of the hollow frame through a bottom wall of the hollow frame.

Description

technical field [0001] The present invention relates to a vehicle battery unit in which a battery is supported on a battery unit main body. Background technique [0002] According to the following Patent Document 1, there is known a structure in which, when a battery is stored in a recess for storing the battery, the battery is supported so as to float from the bottom surface of the recess to prevent the battery from being immersed in water, and the battery is placed in the recess. The drain port provided on the lower wall of the vehicle is provided with a check valve that only allows drainage from the side of the recess to the outside of the vehicle. [0003] [Patent Document 1] Japanese Patent Laid-Open No. 2007-331719 [0004] However, since the invention described in the above-mentioned Patent Document 1 supports the battery so that it floats from the bottom surface of the recess for storing the battery, it is necessary to form a space between the bottom surface of the ...
