The middle accurate positionin for exchanging electric battery 3 and battery settling groove 11；It is positioned to moreover, because changing battery 3 with battery settling groove 11
Accurately, the connector for changing battery can also be avoided to be damaged.
In addition, the utility model embodiment also provides a kind of localization method.The localization method can be real by above-mentioned positioning device
Apply example execution.The localization method mainly includes step S100 and step S110.Wherein:
S100: control platform 21 moves in the horizontal plane, so that positioning mechanism 23 matches with location structure 12.
Specifically, this step S100 may include:
S101: battery 3 will be changed using elevating mechanism 22 and is lifted to the first predetermined altitude；
S102: control platform 21 moves in the horizontal plane, and positioning pin rod 231 is aligned with location hole.
S110: in the case where positioning mechanism 23 and location structure 12 match, control elevating mechanism 22 will change battery 3
It is lifted to battery settling groove 11.
Specifically, this step S110 may include:
S111: in the case where positioning pin rod 231 is aligned with location hole, control elevating mechanism 22 will change battery 3 and lift
To the second predetermined altitude, and positioning pin rod 231 is protruded into location hole；
S112: with set rate, controlling the lifting of elevating mechanism 22 and change battery 3, and retract at the same time positioning pin rod 231, until
It changes battery 3 and reaches third predetermined altitude, so that changing battery 3 is packed into battery settling groove 11.
In step S112, elevating mechanism 22, which lifts, changes the big of the speed of battery 3 and the speed of retraction positioning pin rod 231
It is small equal and contrary, so that the retraction for carrying the rising and positioning pin rod 231 of changing the platform 21 of battery 3 keeps one
It causes, it can be ensured that one end of positioning pin rod 231 is in positioning hole always, so as to more accurately realize that battery and battery are pacified
Positioning between tankage.
Specifically, changing electric car carries battery 3, it is moved to below the vehicle body of electric vehicle 1.The flat platform for carrying battery 3
21 are lifted to the first predetermined altitude by elevating mechanism.When positioning pin rod 23 is driven by the driving part 24, to electric vehicle 1
Vehicle body direction is stretched out.When platform 21 rises to the second predetermined altitude, determining for electric vehicle 1 is inserted on the head 231 of positioning pin rod 23
Position hole 12.Platform 21 is increased with First Speed；Positioning pin rod 23 is declined simultaneously with synchronous speed.In this process, platform 21
The speed that the speed and positioning pin rod 23 of rising decline is consistent (the speed that the speed and positioning pin rod 23 that platform 21 rises decline
The size of degree is identical and contrary).The stopping when platform 21 rises to third predetermined altitude.At this point, it is complete to change battery 3
Electric battery settling groove 11 is changed in merging.Electromagnet 24 powers on actuation, controls the platform 21 and stops floating, by platform 21 and changes electric car
It is mutually fixed.When changing battery 3 and being fixed, positioning pin rod 23 is retracted, and carry out locking operation, to complete to change battery 3
Installation.
In an alternative embodiment, above-mentioned localization method can also include:
S120: it in the case where being remained stationary by controller control platform 21, controls the positioning pin rod 231 and is retracted
Movement；
S130: it exchanges electric battery 3 and is locked.
In the present embodiment, after changing battery settling groove 11 that battery 3 is loaded on 1 vehicle body of electric vehicle, can pass through
Controller is motionless to keep platform 21 to stablize, for example, it is motionless to keep platform 21 to stablize to control electromagnet 24 by controller；This
When, it changes battery 3 and keeps stablizing；Then, positioning pin rod 231 is retracted；It finally exchanges electric battery 3 to be locked, to complete to change
Electric car is electrically operated to changing for electric vehicle 1.
In conclusion the utility model embodiment utilizes the mutual cooperation between platform 21 and elevating mechanism 22, and pass through
The matching of the location structure 12 on positioning mechanism and 1 vehicle body of electric vehicle on platform 21, Lai Shixian change battery 3 and electric vehicle 1
The alignment of battery settling groove 11 on vehicle body, and then realize and exchange electric battery 3 and battery settling groove 11 in changing electric process
It is accurately positioned；The connector that can also accurately avoid changing battery is positioned to battery settling groove 11 moreover, because changing battery 3
It is damaged.
