Rail transit vehicle and battery pack compression plate fastening mechanism thereof

Abstract

The invention discloses a battery pack compression plate fastening mechanism of a rail transit vehicle. The battery pack compression plate fastening mechanism comprises a battery cabinet, a pluralityof partitions arranged horizontally in the battery cabinet and used for mounting batteries, and a plurality of compression plate components arranged on the partitions. The compression plate componentsare arranged in included-angle positions of the batteries on the partitions and are used for clamping included-angle regions of the corresponding batteries. Therefore, the independent compression plate components arranged on the partitions help fixedly fasten the included-angle regions of the batteries; compression plates are simple in structure and convenient to operate; main parts of the batteries are exposed, so that it is convenient for maintenance personnel to observe and operate the batteries; the compression plate components are used for fastening the corresponding batteries respectively, no cooperation is required, and accumulation of mounting errors is avoided. The invention also discloses a rail transit vehicle, having the advantages above.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a fastening mechanism for a battery pack pressing plate of a rail transit vehicle. The invention also relates to a rail transit vehicle. Background technique [0002] With the development of China's machinery industry, more and more machinery and equipment have been widely used. [0003] In the technical field of rail transit, there are many kinds of rail transit vehicles, including trains, high-speed rails, subways, light rails, trams, locomotives, etc. Rail transit vehicles are generally driven by electricity. In order to ensure a stable power supply at all times, rail transit vehicles can not only be connected to cables throughout the entire process, but also generally equipped with backup power sources, namely batteries. [0004] At present, in order to ensure the stable electrical connection between the battery and the electrical components, when the battery is instal...

AI Technical Summary

Problems solved by technology

For example, although the integral pressure plate can fix the battery very well, its structure is bulky, which is not conducive to installation and maintenance. At the same time, it will block the battery, making it impossible for maintenance personnel to observe the state of the battery

Although the existing split-type pressure plate structure is simple and light, it often requires multiple pressure plates to be used together to securely fix the multi-layer battery. This will cause system errors to gradually accumulate due to the existence of manufacturing tolerances, resulting in the inability of some pressure plates to cooperate effectively.
