Abstract

The invention relates to a quick-change locking mechanism for a power battery. The quick-change locking mechanism comprises a fixing assembly and a locking assembly, wherein the fixing assembly comprises a push rod, a first elastic piece and a fixing block; s groove is formed in the upper surface of the end, close to the locking assembly, of the push rod; the locking assembly comprises a locking shaft and a sliding block; the locking shaft comprises a hemispheroid and a cylindrical shaft which are coaxially arranged; the sliding block is sleeved on the cylindrical shaft and is provided with ahorizontal table board and a cambered surface which form an angle with each other; in a locking state, the push rod is respectively clamped with the horizontal table top and a lower surface of the hemispheroid, and a lower edge of the hemispheroid is clamped in the groove of the push rod; in the separation state, the arc surface makes contact with the push rod, and the push rod slides on the arc surface to achieve separation. The mechanism is advantaged in that installation reliability of the locking mechanism can be improved, and the occupied space of the locking mechanism can be reduced through a simple structure.

Description

Technical field[0001]The invention relates to the technical field of battery replacement for electric vehicles, and in particular to a quick locking mechanism for a power battery box and a vehicle body.Background technique[0002]At present, the charging time of electric vehicles is too long compared with the refueling time of traditional fuel vehicles, so there is the problem of electric vehicle cruising range anxiety. The industry is developing fast replacement technology for power battery packs, especially for operating vehicle users, which can greatly shorten the charging time.[0003]The Chinese patent with publication number CN109624779A discloses an automobile battery replacement device and an electric vehicle. The battery is locked by the sliders on both sides that are inserted into the pin slots of the pins, and the gravity of the battery pack and the slider are released from the pins on the pins. The card slot realizes battery unloading. In this solution, the push rod 5 needs ...
