Description

Power battery weighing mechanism

Technical Field

The utility model relates to a power battery weighing machine constructs belongs to power battery weighing technology field.

Background

At present, the scale with the tray is used for weighing the power battery, the weighing sensor is rigidly connected with the tray, and the single mass of the power battery is large, so that impact force can be directly transmitted to the weighing sensor through the tray in the process of placing the power battery when the power battery is weighed, so that the weighing sensor exceeds a bearing range and permanent faults occur. Therefore, the weighing mechanism with the flexibly connected tray is designed, impact on a weighing sensor in the process of placing a power battery can be reduced, and the purpose of protecting the weighing mechanism is achieved.
