Reinforcement unit for side members of electric vehicles

Abstract

The invention relates to a reinforcement unit for a side member of an electric vehicle. The stringer includes a stringer inner panel and a stringer outer panel respectively disposed at lower and opposite ends of the central floor panel. The reinforcing unit includes a reinforcing pipe member and a connecting device, and the reinforcing pipe member is arranged between the longitudinal beam inner panel and the longitudinal beam outer panel along the length direction of the vehicle body; the connecting device includes a plurality of fixing brackets and a plurality of pipe nuts. The attachment means secures the reinforcing tube member to the stringer inner panel.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2016-0152865 filed at the Korean Intellectual Property Office on November 16, 2016, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention generally relates to a reinforcement unit for a side member of an electric vehicle, and in particular, to a reinforcement unit for a side member of an electric vehicle for improving side impact performance. Background technique [0004] Generally, an electric vehicle is driven by an electric motor powered and driven from a battery. [0005] Electric vehicles may, for example, include plug-in hybrid electric vehicles (PHEVs), battery electric vehicles (BEVs), fuel cell electric vehicles (FCEVs), and the like. [0006] A high-voltage battery pack (hereinafter, referred to as a battery pack) is installed in an electric vehicle that is driven using a dri...

Problems solved by technology

[0010] However, the underbody of the electric vehicle according to the conventional art requires an additional installation unit to install the battery box together with the side members on the lower part of the center floor panel through the battery cross member, and accordingly, the number of parts and components for assembling the installation unit The number of assembly processes increases, resulting in an increase in the weight of the vehicle body

[0011] Therefore, the underbody of the electric vehicle requires a space for components such as a mounting unit for mounting a battery pack and a space for forming a gap for suppressing generation of noise between the battery box and the center floor panel, Therefore, the arrangement of the battery plates cannot be freely designed and the improvement of the capacity of the battery pack is restricted.

[0012] In addition, in the underbody of an electric vehicle according to the conventional art, the battery pack is simply supported through the lower part of the center floor panel by the longitudinal beam together with the battery beam, so when a side collision occurs, it is not sufficiently ensured against the impact. safety and durability of the load, resulting in damage to the battery pack
