The stopper 3232 passes through the buffer member 324 in a direction perpendicular to the deformation direction of the buffer member 324. The motion stroke of the limiting element 3232 is limited by the limiting waist groove 32211.
The linkage mechanism 300 preferably includes a relief or bumper for enabling the second unlocking mechanism 200 to move within a range when the first unlocking mechanism 100 is moved. In this embodiment, the yielding waist slot 311 of the first linking unit 310 belongs to the yielding part; the buffer member 324 of the second linkage unit 320 belongs to the buffer portion; they act as a yield or buffer. In other embodiments, the relief portion or the buffer portion may be disposed at other positions, such as between the first unlocking mechanism and the linkage mechanism, between the second unlocking mechanism and the linkage mechanism, and the like.
The unlocking process of the unlocking device 10 is briefly explained below with reference to the drawings:
from the initial position shown in fig. 1, the unlocking mandril 110 (containing a spring therein) moves to the left, the unlocking mandril 110 contacts with the lower convex part of the lock connecting rod 53, so that the unlocking mandril 110 retracts downwards, and because the primary lock shaft of the battery pack is tightly matched with the primary lock tongue 52 at the moment, the force of the unlocking mandril 110 is not enough to jack up the lock connecting rod 53, the unlocking mandril 110 moves to an unlocking point 531, and the lock connecting rod 53 does not move; in the process, the linkage connecting plate 340 and the first linkage unit 310 both move leftwards, the abdicating waist slot 311 slides relative to the abdicating slider 321, and the abdicating slider 321 does not start moving yet.
Then, a corresponding mechanism on the battery changing platform 80 acts on the battery pack, so that the first-stage locking tongue 52 is not tightly matched with the first-stage locking shaft any more, the force of the unlocking ejector rod 110 can enable the locking connecting rod 53 to move upwards to the left, the first-stage locking tongue 52 rotates to realize first-stage unlocking, the unlocking ejector rod 110 can follow the left, and the following distance is about 20 mm; in the process, the linkage connecting plate 340 and the first linkage unit 310 both move leftwards, and meanwhile, the end part of the abdicating waist slot 311 is in contact with the abdicating slider 321, so that the second linkage unit 320 is also driven to move leftwards, the swing arm 220 rotates, the unlocking part 231 slides, and the second-stage locking tongue 62 rotates to realize second-stage unlocking.
Above, the primary locking mechanism 50 and the secondary locking mechanism 60 can be unlocked synchronously.
