A locking method for mounting a battery to a fixing seat of an electric vehicle using a locking device, the locking device comprising:
- a lock base configured to provide a locking position, and comprising a lock body having a surface provided with a lock groove recessed towards the inside of the lock body, the lock body being provided with a lock tongue groove and a lock tongue movably mounted in the lock tongue groove, and the lock tongue groove being in connection with the lock groove;
- a lock shaft comprising a shaft rod, the shaft rod being configured to be inserted into the lock groove of the lock base to perform unlocking and locking;
- and
- a lock connecting rod movably connected with the lock base through the lock tongue, wherein lock tongues of a plurality of lock bases are controlled simultaneously by a single lock connecting rod to perform synchronous locking of the plurality of lock bases, and wherein the lock connecting rod comprises a rod member, and a second positioning steel magnet is mounted on the rod member,
- wherein the locking method comprises:
- moving the battery from a bottom of the electric vehicle into the fixing seat under a lifting action of a battery-changing mobile platform;
- and
- inserting the shaft rod of the lock shaft around the battery into the lock groove through an opening of the lock groove on the lock base;
- and
- wherein after moving the battery from the bottom of the electric vehicle into the fixing seat under the lifting action of the battery-changing mobile platform, the locking method further comprises:
- pushing the lock connecting rod to move upwards by an unlocking member, and driving the lock tongue to open the opening of the lock groove;
- and
- determining whether the lock connecting rod is currently in an unlocked state or in a locked state by the second positioning steel magnet stays at or passes through a sensing device provided on a moving track of the second positioning steel magnet, when the rod member is moved.
An unlocking method for unlocking a locking device that mounts a battery to a fixing seat of an electric vehicle, wherein the locking device comprises:
- a lock base configured to provide a locking position, and comprising a lock body having a surface provided with a lock groove recessed towards the inside of the lock body, the lock body being provided with a lock tongue groove and a lock tongue movably mounted in the lock tongue groove, and the lock tongue groove being in connection with the lock groove;
- a lock connecting rod movably connected with the lock base through the lock tongue, and configured to control lock tongues of a plurality of lock bases simultaneously and perform synchronous locking of the plurality of lock bases, wherein the lock connecting rod comprises a rod member, and a second positioning steel magnet is mounted on the rod member;
- and
- a lock shaft comprising a shaft rod, the shaft rod being configured to be inserted into the lock groove of the lock base to perform unlocking and locking,
- wherein the unlocking method comprises:
- making an unlocking device on a battery-changing mobile platform contact the lock connecting rod and push the lock connecting rod to rise, so that the lock tongue leaves the lock groove;
- and
- moving the battery to withdraw the shaft rod from the lock groove, and completing a battery removal process;
- and
- wherein during rise of the lock connecting rod, the rod member is moved, and the second positioning steel magnet stays at or passes through a sensing device provided on a moving track of the second positioning steel magnet to determine whether the lock connecting rod is currently in the unlocked state or in the locked state.
