Embodiment Construction

[0034] A configuration example of the battery protection structure according to the present invention will be described based on the following drawings.

[0035] figure 1 (a) is a perspective view of the battery protection structure according to the present invention, and the cover member 50 is shown as a perspective view in order to understand the internal battery module 1 .

[0036] figure 1 (b) shows the relationship of the protection member 10 which consists of several protection frames 11-15, and the side frames 21 and 22.

[0037] figure 1 (c) shows the protection member 10 alone.

[0038] respectively by figure 2 (a) shows figure 1 The A-A line profile of (a), by image 3 (a) shows a part of the B-B line sectional view.

[0039] The protection member 10 in this embodiment is an example in which five protection frames 11 to 15 are connected, but the number of connection may be selected according to the loading capacity of the battery modules.

[0040] The protec...

Abstract

The purpose of the present invention is to provide a battery protection structure that has a high protection effect on a battery mounted on a vehicle and has excellent water repellency. This battery protection structure is characterized by being provided with: a protection member; a plate-shaped waterproof member that overlaps the upper surface side of the protective member; and a battery module mounting part disposed on the upper surface side of the waterproof member, the protective member being formed by connecting a plurality of protective frames each having a hollow cross-sectional shape to each other.

Description

technical field [0001] The present invention relates to a battery protection structure for mounting a secondary battery on a vehicle. Background technique [0002] In the fields of electric vehicles and hybrid vehicles, secondary batteries called battery modules, battery packs, and the like are mounted. [0003] In order to increase the cruising distance that can be traveled on a single charge, it is necessary to increase the mounting space of the corresponding secondary battery, which also increases the weight. [0004] Therefore, in recent years, it has been considered to secure a battery mounting space on the underside of the floor of the vehicle. [0005] In this case, it is necessary to prevent the intrusion of rainwater from the outside. [0006] For example, Patent Document 1 discloses a structure in which an inner peripheral edge and an outer peripheral edge are provided on a battery frame for mounting a battery (battery) and a bottom plate member is fitted therebe...
