Locking system and quick-replacement support assembly with locking system

Abstract

The invention discloses a locking system and a quick-replacement support assembly with a locking system. The locking system is applied to a battery pack. The locking system comprises a first-level locking mechanism, the first-level locking mechanism is provided with a locking linkage part and a locking base, the locking base is provided with an opening and a cavity extending from the opening, andthe opening is used for a lock shaft of the battery pack to enter the cavity. The locking linkage part moves relative to the locking base to open or close the opening and lock or unlock the battery pack. The locking system further comprises a second-level locking mechanism, and the second-level locking mechanism is arranged on a mobile path of the locking linkage part and used for limiting motionof the locking linkage part relative to the locking base so as to lock the battery pack. The quick-replacement support assembly comprises a quick-replacement support and the locking system, and the locking base and the second-level locking mechanism are connected to the two opposite sides of the same edge of the quick-replacement support respectively. The second-level locking mechanism can limit motion of the locking linkage part relative to the locking base, the reliability of the first-level locking mechanism can be improved accordingly, and the fall-off phenomenon of the battery pack is reduced or avoided.

Description

Technical field [0001] The invention relates to the field of battery replacement of electric vehicles, in particular to a locking system and a quick-change bracket assembly containing the locking system. Background technique [0002] The existing battery pack installation methods of electric vehicles are generally divided into fixed type and replaceable type. The fixed type battery pack is generally fixed on the car, and the car is directly used as the charging object during charging. The replaceable battery pack is generally installed in an active manner, and the battery pack can be removed at any time and replaced with a new battery pack. [0003] In the process of replacing a new battery pack, the battery pack is locked and unlocked. Generally speaking, lock shafts are installed on the left and right sides of the battery pack; the locking device is fixed on the quick-change bracket to assemble the quick-change bracket assembly, and the quick-change bracket assembly is installed...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a locking system and a quick-change bracket assembly containing it in order to overcome the defects that the locking device in the prior art has the defects that the primary locking mechanism is easy to fail and the battery pack is easy to loosen or fall off.
