Description

Technical Field

[0001] This utility model relates to the field of power battery technology, and in particular to a power battery frame structure, a power battery pack, and an electric loader. Background Technology

[0002] In the field of new energy loaders, loaders also use clean energy as their power source, with electric technology becoming the mainstream. The primary issues in the application of electric technology are energy storage and range, therefore, the power battery needs to be large enough, and integration and layout become key issues in loader design. However, there are currently many technical problems with the power battery frames on the market.

[0003] First, the existing power battery frame layout is relatively dispersed, which makes packaging difficult. Because the power batteries are scattered, it is difficult to perform unified and effective packaging, making them susceptible to external environmental factors such as water ingress and moisture. Once the battery is exposed to water or moisture, the risk of short circuit and combustion increases significantly, seriously affecting the performance and safety of the power battery, and also threatening the normal operation of the loader.

[0004] Secondly, the existing battery frame design presents significant challenges for battery replacement and maintenance. The battery installation method is not ideal; for example, the orientation of the battery mounting bolts is inconvenient, typically installed vertically. This restricts operating space during power battery replacement, making disassembly and installation difficult and resulting in substantial time and labor costs. Utility Model Content

The battery tray is located inside the battery frame body.

[0009] As a further technical solution, the bottom of the battery frame body is detachably connected to a bottom battery frame by bolts. The bottom battery frame includes a bottom frame battery baffle, a bottom frame battery support plate, and a connecting plate. Three bottom frame battery baffles are vertically arranged.
