Problems solved by technology

Although the rear pillar is also made of metal including the flange, if such a flange comes into contact with the power terminals of the auxiliary machinery battery in a rear collision, a short circuit will occur
Of course, the periphery of the power terminal is covered with a terminal cover made of insulating material, but such a terminal cover may sometimes come off due to the impact when the rear pillar collides with the auxiliary machinery battery
That is, in the prior art, there is still room for improvement regarding the prevention of short-circuiting of the power terminals of the battery during a vehicle rear collision.

Embodiment Construction

[0032] Hereinafter, the mounting structure of the battery will be described with reference to the drawings. figure 1 This is a plan view of vehicle 100 on which battery 22 is mounted. in addition, figure 2 It is a figure explaining the positional relationship between the battery 22 and the rear pillar 12 . In addition, in the following drawings, "Fr" and "Up" mean the front and the upper side of the vehicle, and "In" and "Out" mean the inside and outside in the vehicle width direction.

[0033] Since the battery 22 functions as a power source for auxiliary machinery of the vehicle 100 , it is generally referred to as an “auxiliary machinery battery”. The storage battery 22 is constituted by, for example, a lead storage battery, and its output voltage is about 12V. The battery 22 is combined with a battery cover 24 and the like, which will be described later, to form a battery unit 20 . The battery unit 20 is arranged in a luggage space at the rear of the vehicle.

Abstract

A battery mounting structure has a battery that is placed in a luggage space and that has a positive electric power terminal which protrudes upward near a rear end of the battery, a battery cover thatcovers at least a part of the battery, a rear pillar that is placed at a boundary between a side surface and a back surface of the vehicle and that has a flange which protrudes to a front side, and an insulating sheet that is attached to the battery cover so as to be positioned between the positive electric power terminal and the flange.

Description

technical field [0001] The present specification discloses a battery mounting structure for mounting a battery in a luggage space of a vehicle. Background technique [0002] Among the in-vehicle batteries, there is one that is arranged in a luggage space of a vehicle. For example, auxiliary machinery batteries that supply electric power to auxiliary machinery of the vehicle are mounted in the luggage space of the vehicle. Conventionally, various techniques have been proposed for protecting such a battery when a large impact is applied to the vehicle due to a collision of the vehicle with another object or the like. [0003] For example, Patent Document 1 discloses an auxiliary mechanical battery arranged at a rear portion of a rear wheel house. In this Patent Document 1, in order to protect the auxiliary machine battery in the event of a frontal collision of the vehicle, a ventilation duct is arranged between the rear wheel house and the auxiliary machine battery. In the ...
