Problems solved by technology

In this case, there may be a narrow and low-rigidity area outside the opening of the floor panel, and the vibration of the floor panel may increase due to vibration from the vehicle body side such as coil springs.
[0009] In addition, in the case described in Japanese Patent Laid-Open No. 2010-89567, the floor panel is actually dented, so it is difficult to dent it greatly, and as a result, a large amount of space in the luggage compartment is taken up.

Embodiment Construction

[0027] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Figure 1 to Figure 8 One embodiment of the vehicle-mounted structure of the battery pack according to the present invention is given.

[0028] exist figure 1 and figure 2 In this case, a vehicle 100 includes a floor panel 105 on which a front seat 101 and a rear seat 102 are mounted, which constitutes a floor surface and forms a compartment R. As shown in FIG. The rear portion of the compartment R is configured to be usable as a luggage compartment L that can be opened by opening and closing a hatchback door 109 . This vehicle 100 is configured as a hybrid vehicle, and the large-capacity battery pack 10 is installed in a luggage room L of the vehicle 100 . Here, although omitted in the drawing, the hybrid car supplies electric power through the battery pack 10 to electric components such as an air conditioner installed in the vehicle, performs air c...

Abstract

A vehicle battery pack mounting structure that suppresses vibrations of a floor panel while making a shock absorbing space between the battery pack and vehicle exterior members large by effectively utilizing a space between coil springs. The battery pack mounting structure includes a pair of left and right side members and a cross member for supporting the battery pack. A pair of left and right coil springs is installed at these side members and function as suspension members. The battery pack is installed inside an opening of a floor panel between the coil springs, and also between the coil springs, a front portion of the battery pack has a tapered outer surface that becomes narrower as it enters deeper into a space between the coil springs. The opening of the floor panel also has a tapered edge shape.

Description

technical field [0001] The present invention relates to an on-vehicle structure of a battery pack, and more particularly to an on-vehicle structure of a battery pack that reduces damage to the battery pack and suppresses an increase in vibration caused by a structure for mounting the battery pack during a vehicle collision. Background technique [0002] Electric vehicles and hybrid vehicles equipped with an electric motor as a driving source require a battery pack capable of storing large-capacity power to be installed on the vehicle because electric power is supplied to electrical components installed in the vehicle in addition to the electric motor. [0003] This type of battery pack includes a battery pack that is accommodated in a concave well formed in a floor panel (see, for example, Japanese Patent Laid-Open No. 2010-89567). [0004] In order to ensure as much space as possible for passengers inside the vehicle, the on-board structure of this battery pack is usually i...
