Electric commercial vehicle and electric commercial vehicle split battery pack fixing device

Abstract

The invention discloses an electric commercial vehicle and an electric commercial vehicle split battery pack fixing device. The fixing device comprises a support assembly arranged on a longitudinal member, wherein the support assembly comprises a longitudinal installation plate installed on the ventral surface of the longitudinal member, and a horizontal installation plate, and the horizontal installation plate is installed on the upper wing surface of the longitudinal member. In this way, during battery pack installation, the fixing device can be hung onto the upper wing surface through the horizontal installation plate, then the horizontal installation plate and the upper wing surface are fixed together and the longitudinal installation plate and the ventral surface are fixed together, the fixing device can be hung onto a vehicle body during installation, and support installation difficulty is reduced; meanwhile, the number of fixation points between the support and the vehicle body is increased, and then the rotation of the support relative to the vehicle body is effectively avoided, battery pack installation reliability is improved, and the safety of the whole vehicle and the battery pack is ensured.

Description

technical field [0001] The invention relates to the field of electric commercial vehicles, in particular to a design of a fixing device for a split battery pack of an electric commercial vehicle. The present invention also relates to an electric commercial vehicle comprising the above-mentioned fixing device for the split battery pack. Background technique [0002] The rapid development of the automobile industry has aroused the world's attention to energy and the environment. Pure electric vehicles have the advantages of low noise, no pollution, and high energy efficiency. Practice has proved that vigorously developing pure electric commercial vehicles is one of the important ways to alleviate the pressure on human energy and the environment. . [0003] As the core component of electric commercial vehicles, power batteries play a vital role in the power performance of the vehicle. As we all know, the working environment of some electric commercial vehicles is relatively h...

Problems solved by technology

How to safely and reliably arrange the high-power battery packs on the vehicle is a key technology. The existing split battery packs are often installed in the way of "L"-shaped brackets fixed on the web of the longitudinal beams, that is, The bracket is only fixed on the side of the longitudinal beam through its side. This installation method lacks a positioning structure during the installation of the battery pack, and the assembly is difficult. At the same time, due to the lack of positioning points of the bracket, it cannot effectively prevent the bracket from moving relative to the vehicle. The rotation of the body, and the load distribution is uneven, and long-term work will cause the "L"-shaped bracket to bend and deform
