Problems solved by technology

In the event of a side impact, the inertia of this largely empty space transfers the force of the impact almost entirely to the battery pack, which can cause irreparable damage to the pack or even cause a fire in extreme cases. risk

Embodiment Construction

[0027] Throughout the specification, front and rear are defined in terms of the direction of travel of the motor vehicle. When traveling straight forward, the vehicle travels from rear to front along the X axis. Furthermore, the vehicle is considered to rest on a level ground with an X-axis and a Y-axis. The terms "lower" and "upper" refer to the vertical axis Z.

[0028] figure 1 The vehicle 1 is schematically shown from below, at least the vehicle part is shown with a rear wheel axle 3 arranged adjacent to a battery assembly 20, both of which are connected to the underbody frame of the vehicle structure. The battery assembly 20 is a module realized in a single part, and is preferably arranged in a central position of the vehicle along the transverse axis and close to the rear wheel axle 3 in order to maintain excellent grip of the vehicle equipped with the electric drive system. The underbody structure comprises skirts 31 , 32 connected to each other by a transverse barr...

Abstract

The invention relates to an arrangement of a body understructure of a vehicle (1) comprising a device (2) for protecting a set of batteries (20), the body understructure laterally comprising side sills (31), at least one transverse barrier (33) connecting the side sills to one another, as well as a floor (34) arranged to cover the side sills and the barrier, the vehicle comprising at least one functional element (40) extending under the understructure of the vehicle, the protective device (2) comprising at least one insert (10) arranged between a side sill (31) and a lateral edge (23) of the battery assembly (20) along an axis transverse to the vehicle, characterised in that the insert (10) is shaped according to the functional element, in particular by means of at least one recess intended for receiving the functional element (40). The invention also relates to a vehicle comprising such an arrangement.

Description

technical field [0001] The present invention relates to the field of vehicles, and more particularly to motor vehicles. The invention is most particularly applicable to the design of vehicles with fully electric or partially electric propulsion, requiring an integrated battery pack. [0002] The invention relates to an arrangement of a vehicle underframe structure with a battery and means for protecting the battery assembly. Background technique [0003] It is known that vehicles, in particular motor vehicles, have a drive that uses electrical energy stored in a battery pack. In order to maintain a certain load capacity or even maintain a good grip, it is known to arrange such battery packs under the body of the vehicle. This also allows for maintenance, or even quick replacement of the battery pack if required. Although such an arrangement has proved to be advantageous today, such an arrangement is disadvantageous for the protection of the battery pack in the event of a ...
