Lithium battery pack shell and lithium battery pack specialized for industrial vehicle

Abstract

The invention provides a lithium battery pack shell and a lithium battery pack specialized for an industrial vehicle. The lithium battery pack shell comprises a battery case, a cover plate, a side shock absorbing mechanism, connecting mechanisms and a connecting frame. The bottom plate in the side shock absorbing mechanism is installed on the side surface of the battery case through a spring I, and the top plate is rotationally installed on the bottom plate through an I-shaped connecting frame and the I-shaped connecting frame is provided with a torsion spring. A plurality of connecting mechanisms are equally divided into two rows and installed on the side surface of the battery case. The two touching blocks and the two limiting plates in each connecting mechanism are movably installed onthe two sides of the bracket. Two baffles are movably installed on the top of the bracket and are respectively in contact with the two limiting plates. Two connecting frames are respectively installedon one side of the battery case. The vibration impact between the two adjacent battery cases can be effectively eliminated through the I-shaped connecting frames and the torsion spring between the bottom plate and the top plate, and the limiting plates are driven away from the baffles through the touching blocks on the bracket and thus the effect of automatic fixed connection can be achieved.

Description

technical field [0001] The invention relates to the technical field of battery components, in particular to a lithium battery case and a lithium battery pack for industrial vehicles. Background technique [0002] Publication number CN105470427B provides a new energy battery pack that is easy to install and disassemble. When the battery pack is installed, the ribs of the battery plates are clamped in the vertical slots, and the contacts on both sides are respectively connected to the contact block A and The contact block B is connected to form the connection of several battery plates, thereby realizing the process of quick installation, but the contact block of the battery pack is provided with a spring at the connection part of the battery electrode, and the battery pack is prone to shake up and down when it is used in an engineering vehicle. Furthermore, a long-term frictional contact will be formed between the battery electrode and the contact block, which will easily dama...
