Locking device and electric automobile

Abstract

The invention provides a locking device and an electric automobile. The locking device comprises lock bases, a lock connecting rod and lock shafts, wherein each lock base is used for providing a point to be locked and comprises a lock body; a lock groove which is concave toward the inner part of the corresponding lock body is arranged on one face of the corresponding lock body; each lock body is internally provided with a lock tongue groove and a lock tongue which is movably mounted in the lock tongue groove; the lock tongue grooves are communicated with the lock grooves; the lock connecting rod is movably connected with the lock bases through the lock tongues and comprises a rod part; the rod part drives the lock tongues to move in the lock tongue grooves under the action of an external force; each lock shaft comprises a shaft seat and a shaft rod; and the shaft rods are vertically arranged on the surfaces of the shaft seats, and the shaft rods are inserted into the lock grooves of the lock bases and are used for locking. According to the locking device and the electric automobile, the plurality of lock shafts, which are distributed at a side edge of a battery, are utilized and are inserted into the plurality of lock bases located on the electric automobile, so that the battery is fixed on the electric automobile; and the plurality of lock shafts can be automatically locked by the lock bases at the same time through utilizing the movement of the lock connecting rod, so that the installation efficiency and detachment efficiency of the battery are greatly improved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a locking structure for locking a battery of an electric vehicle on the electric vehicle, and an electric vehicle using the locking device. Background technique [0002] The battery installation methods of existing electric vehicles are generally divided into fixed type and replaceable type, wherein the fixed type battery is generally fixed on the car, and the car is directly used as the charging object when charging. And replaceable battery generally adopts the mode of movable installation, and battery can be taken off at any time, to replace or charge, after changing or charging finishes, install on the car body again. [0003] The current battery replacement methods include manual and automatic operations. Regardless of the method, the battery is installed on the chassis of the electric vehicle. After installation, the battery needs to be locked on the vehicle body. Because th...
