A rail transit vehicle and its battery pack pressing plate fastening mechanism

Abstract

The invention discloses a fastening mechanism for a battery pack pressing plate of a rail transit vehicle, comprising a battery cabinet, a plurality of spacer plates arranged horizontally in the battery box and used for installing batteries, and spacer plates arranged on the spacer plates of each layer A plurality of pressing plate assemblies, each of the pressing plate assemblies is respectively arranged on the spacer plate at the angle position of each of the storage batteries, and is used for clamping the angle areas of the corresponding storage batteries. In this way, the compression and fixation of the angled area of ​​each battery is realized through several independent pressure plate assemblies arranged on the spacer plate. The structure of the pressure plate is simple and the operation is convenient. At the same time, the main part of the battery is exposed, which is convenient for maintenance personnel to observe. operation; moreover, each pressing plate assembly is used to fasten its corresponding storage battery respectively, and does not need to be used in conjunction to avoid the accumulation of installation errors. The invention also discloses a rail transit vehicle, the beneficial effects of which are as described 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.
