Description

Technical Field

[0001] This utility model relates to the field of battery mounting bracket technology, and in particular to a rear-mounted sunken mounting bracket for an electric loader battery. Background Technology

[0002] Electric loaders, as a type of new energy construction machinery, replace traditional fuel engines with electric motors to provide power, with battery packs as the main energy source. However, due to the special working conditions and capabilities of loaders, their energy consumption is relatively high. In order to improve the working time and efficiency of loaders, they often need to be equipped with large-capacity battery packs, but large-capacity batteries are often accompanied by large size.

[0003] Existing electric loaders typically place batteries above or inside the rear frame, requiring the frame to be lengthened to accommodate more batteries. This results in low space utilization and insufficient structural rigidity. Furthermore, the counterweight structure is separate from the battery compartment, failing to fully utilize the battery's own weight as a balancing counterweight. Additional cast iron or concrete counterweights are required, which is costly and takes up space. Moreover, the existing four battery packs are first connected by stacked brackets on the outside before being hoisted and fixed onto the frame as a whole, which increases the difficulty and strength of connecting the battery pack brackets to the frame. Utility Model Content

[0004] In order to overcome at least one of the defects mentioned above in the prior art, this utility model provides a rear-mounted sunken mounting bracket for electric loaders, which solves the problem that connecting the battery pack bracket to the vehicle frame with externally stacked brackets and then hoisting it onto the vehicle frame as a whole increases the difficulty and strength of the connection.
