The invention provides a connecting rod self-locking limiting structure, a limiting column, a battery replacing fixing bottom support and a battery replacing lorr.The connecting rod self-locking limiting structure comprises a connecting rod assembly and a limiting rod assembly, the connecting rod assembly comprises a first connecting rod, a second connecting rod and a third connecting rod, one end of the first connecting rod is rotationally arranged, the other end of the first connecting rod is hinged to one end of the second connecting rod, and one end of the third connecting rod is hinged to the first connecting rod; the lock head comprises a rotating part, a connecting part and a clamping and locking part which are connected in sequence, the rotating part is rotationally arranged, and the other end of the second connecting rod is hinged to the connecting part; the driving assembly is connected with the connecting rod assembly through a third connecting rod and drives the connecting rod assembly to rotate through the third connecting rod, and when the first connecting rod and the second connecting rod rotate to the self-locking position where the axial directions of the first connecting rod and the second connecting rod are located on the same straight line, the clamping and locking part of the lock is pushed out and abuts against the limiting body. The problem that a battery locking device in the prior art is insufficient in locking force and poor in battery height compatibility due to the fact that the battery locking device occupies a large base space is solved.

    本发明提供一种连杆自锁限位结构、限位柱、换电固定底托及换电卡车,连杆自锁限位结构,包括:连杆组件,包括第一连杆、第二连杆以及第三连杆,第一连杆的一端转动设置,另一端与第二连杆一端铰接,第三连杆的一端铰接于所述第一连杆上;锁头,包括依次连接的转动部、连接部以及卡锁部,其中,转动部转动设置,第二连杆的另一端铰接于连接部上;驱动组件,驱动组件通过第三连杆与连杆组件相连,并利用第三连杆带动连杆组件转动,并在第一连杆以及第二连杆转动至其轴向处于同一直线的自锁位置时,锁头的卡锁部推出并与限位主体抵接;本发明解决了现有技术电池锁紧装置锁紧力不足的问题以及占用底托空间大造成的电池高度兼容性差的问题。
