Description

Technical Field

[0001] The utility model relates to the technical field of a stacked assembly bracket for power storage batteries, in particular to a stacked assembly bracket for power storage batteries. Background Art

[0002] The power batteries of new energy buses are generally installed on the power battery pack bracket of the vehicle frame in the form of power battery packs. The weight of a power battery pack is about 200kg. A new energy vehicle generally needs to install multiple power battery packs according to the configured power. At present, the installation threaded holes of the power battery packs of buses are vertically downward. The general fixing method is to drop the power battery pack on the fixed bracket, pass the bolts from the bottom of the fixed bracket and lock them into the fixed threaded holes of the power battery pack to fix the power battery pack on the fixed bracket. The installation space of each power battery pack must be reserved at a high enough height so that the assembly workers can lie flat in the installation space of the power battery pack on the lower layer to fix the fixing bolts of the power battery pack on the upper layer. When the upper power battery pack needs to be repaired later, the above actions need to be repeated, which causes great inconvenience. This not only increases the production rhythm of the general assembly line, but also increases the length of the general assembly line.

[0003] At the same time, the liquid cooling plate inside the power battery pack is designed to be under the power battery pack. When the power battery pack cooling system is working, the steel plate on the bottom mounting surface will transfer the heat from under the vehicle or outside the vehicle to the liquid cooling plate of the lower power battery pack, reducing the cooling efficiency of the liquid cooling plate of the lower power battery pack. It also increases the imbalance of the working environment temperature of the battery cells inside the upper and lower power battery packs, thereby affecting the working life of the power battery of the entire vehicle.
