Description

Technical Field

[0001] The utility model relates to the technical field of battery installation and fixing, in particular to a battery installation frame for an electric loader. Background Art

[0002] Compared with fuel loaders, electric loaders do not have engines and torque converters. Instead, the power battery provides power for the entire machine, drives the motor, and controls the vehicle's travel and working systems, achieving zero emissions and low noise during the working process. The power battery is in the form of a pack. A single pack has a fixed voltage and capacity, and the required total capacity is obtained by connecting multiple packs in series and in parallel.

[0003] The total capacity of the power battery is a key performance parameter of the electric loader. The larger the total capacity, the longer the working life of the whole machine. Since the power consumption of the electric loader is different under different working conditions, in order to meet the normal working life, it is necessary to develop the same model of electric loaders with different power configurations to meet the needs of various working conditions; in addition, the high-voltage module inside the battery pack box has low strength and requires appropriate shock absorption protection to avoid battery damage due to excessive vibration or impact; at the same time, the working conditions of the loader are very harsh. If corrosive foreign matter such as dust enters the battery frame and accumulates, it will cause accumulation and corrosion at the battery terminals, causing battery system failure.

[0007] According to an embodiment of the utility model, upper baffles, side panels and bottom baffles are respectively installed in a packaged manner at gaps in the top, sides and bottom of the multi-layer frame assembly.

[0008] Beneficial effects: The electric loader battery installation frame provided by the utility model is assembled by stacking multiple layers of frames in sequence along the height direction to form a multi-layer frame assembly. Two battery packs can be hoisted in advance on each layer of the frame. By adjusting the number of layers of the frame, the configuration of different battery capacities of the whole machine can be met, and the application range is wide. In addition, by installing shock absorbers at the bottom of the multi-layer frame assembly, the vibration of the entire battery installation frame can be effectively reduced to prevent the high-voltage module inside the battery pack box from being damaged due to excessive vibration or impact.
