The present application relates to the technical field of battery frame, especially to a
lithium battery anti-collision and lightweight bearing frame and battery module, the battery frame comprises: a main frame, the cross section is a two-dimensional negative Poisson's ratio structure with
impact resistance, forming a plurality of battery accommodating unit rows; a
functional module is connected between adjacent battery accommodating unit rows, the inside is provided with a function piece which can be broken under
impact to passively absorb energy, and an active trigger
assembly which can be controlled to trigger to actively release the connection and cause structural
instability; a detection unit for real-time monitoring of
frame size, acceleration and temperature; a
control unit for dynamically evaluating
system load based on
monitoring data and intelligently deciding to trigger a graded
energy absorption response. Through the synergistic effect of the negative Poisson's ratio structure, the breakable function piece and the intelligent
active control, the present application realizes the breakthrough from passive bearing to
active safety protection, significantly improving the collision safety and reliability of the
battery system.
